Firefox Community Forum

I was reading https://embracethered.com/blog/posts/2024/m365-copilot-prompt-injection-tool-invocation-and-data-exfil-using-ascii-smuggling/ and hovered over the hxxtp://wuzzi[.]net link.

I noticed that the status bar on firefox shows the same text as the on-page text. It doesn't render the unicode url in full. I tried finding a bug describing this, but couldn't find one.

Sample URL:

Today, Firefox stopped playing audio on Facebook videos and won't play Netflix videos at all (Netflix error code: F7701-1003). Youtube works fine and has audio, but several other video sites I've tried have video but no audio. It was all working fine yesterday and I haven't changed any settings.

These websites work fine with both audio and sound on Microsoft Edge on the same laptop, so this is a problem exclusive to Firefox. OS is Windows 11 Home 23H2, Firefox is latest version (129.0.2)

Things I've tried: 1. Refresh Firefox settings 2. Download and install fresh copy of Firefox 3. Toggle DRM content in setting on/off - no difference no matter what is selected 4. Ensure that 'remember history' is selected 5. Check for Windows updates 6. Uninstall audio driver, restart and fresh install of audio driver 7. Ensure it's not in private mode 8. Turn off all extensions 9. Check volume mixer allows sound for Firefox 10. Clear the cache and cookies

I can't find any more suggestions on the internet, so any further suggestions welcome!

I'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

I created a few virtual hosts and sites on my local machine and this is working perfectly.

Problem is with Firefox, when I enter non-existant url in address bar, Firefox force me to search and don't let me to open the url, but I need to go to this url for testing, developing, etc...

Any solution?

After my Windows 10 laptop being in sleep mode I found my background picture changed and all my Firefox tabs missing (while my bookmarks, add-ons, history etc. saved, and all other apps functioning properly). Recently Closed Windows menu was inactive and using Restore option in Library had no effect (despite availability of recent saves).

I found out that Mozilla folder was just missing in %appdata% (e.g. Profile Folder in about:support leaded to a non-existent directory). No manual changes to Firefox settings/data were made and no new profiles created.

What might be the problem and are there any ways to restore my tabs?

I have tried watching videos through chrome and other browsers by searching something via duck duck go and watching that video on duck duck go, and it works on other browser so it must be specific to firefox.

Whenever I try to watch a video, in the drop down bar firefox select to mute audio for some reason. I then select 'allow audio and video' and refresh the page but the video is still muted for some reason. This also happens when I try to use other video sites. This has only started to happen recently in the past two days (and yes I am updated to the latest version of firefox).

duplicate of /questions/1460807 thread.

Would you help me signing up? I already created Mozilla Support account a while ago. But I'm still having that same problem.

So, my browser is disabled. I can open it, but if I type anything in the adress bar (the home menu with recomendations and the search tab doesn't pop up) it will process the information, but then stop and gives me a blank screen. I send an image of it. For example if I type https://www.google.com the tab will go white and I can't do anything about it. In the apliccation menu, the only thing I can do is to go into troobleshooting mode by clicking the Help tab. Everything else (except for the new tab or window tool) is disabled. I beleive it is coused by the fact I can't open any website and those tabs are links. Please write back.

UPDATE - - problem solved - - Using Firefox Troubleshooting Mode I found that the problem was ''''caused by an added extension '''' which has been turned off (I hope) One thing I don't understand though is that I fixed this in Firefox but it also fixed it in Chrome. All images show up in both, so how does one browser fix a second browser? I have yet to check Safari but I never use that one anyway, so I'm not going to push my luck! Thanks Terry.

- - - I have a LOT (hundreds) of images that do not show up on many pages and each one is labeled,

403 Forbidden in the Network Monitor.

There are images that do show up on the same pages and the amount varies.

Those are labeled with a green 200.

What causes this and how can I fix it so they all show on the pages?

and do I have to fix each and every one? That would take months.

Thanks

Hi, not sure what I'm doing wrong, but my logins and passwords simply will not synch between devices. I principally use a desktop Win10 machine, and an iOS version of Firefox. Have double-checked settings on both devices, tried forcing a manual sync from each to the other, all to no avail. Any ideas on what I need to do differently? TIA.

When I search directly from the address bar, the search always defaults to google.com/....whatever I am searching for. But even though my region is set to United Kingdom, my search results are definitely not the same as if I were to navigate to www.google.co.uk and then search for the same string. Is there any way for the default google search to use google.co.uk rather than google.com Thanks?

This was one of our primary suppliers for technology. Contacted them they just said "suck it up, princess".

Recently AWS started doing "human verification" on all VPN traffic to websites they host on their CDN(s). This results in all our Windows 10 PCs running Firefox ESR 102.13.0 going into an endless "Human verification" loop, never able to access the website.

On the Windows 2012 R2 server we have access to the above website works. We see "human verification" for a second or two and then the website is displayed.

So, copied my profile from a Windows 10 PC that doesn't work to the server and it works.

I've tried with tracking protection off. Turned off all adblockers, run in safe mode with all addons disabled, cleared my cache, deleted all cookies Created a new profile and still no go. Turned off Windows firewall, moved hosts file out of the way. Still no go. Also deleted prefs.js to run firefox as completely vanilla without any changed preferences.

I'm not inclined to install malware, so chrome based browsers are not an option. They are actually blocked so I couldn't install them even if I wanted to.

All PCs are on 21H2 3208. Upgrading is not an option at this time. PCs will be upgraded mid-late 2024.

All PCs are required to be connected to VPN at all times as we work from home. Being on call late into the night also means we can't just disconnect. We use NordVPN. Yes I know there is a lot of paranoia about VPNs being the source of all online crime. I just think that's an over-generalization. A convenient excuse.

https://www.scorptec.com.au did a similar thing earlier this year, but at least with them we get a captcha and can get to their site.

Could this be a browser issue, or is this more likely to be a Windows 10 issue? Also updated Windows 10 to latest patch each month and it's been the same for three months.

With previous versions of Firefox (before 108.0.1) I was able to make changes with about:config to allow a default domain id .com to be added to my Internet query. Example I enter cnn and would get cnn.com and assess the website. WIth 108.0.1 I enter cnn and Firefox cannot find the site. The about:config changes I made are:

 set browser.urlbar.autofill to false, set keyword.enabled to false and set browser.fixup.alternate.enabled to true. 

The changes are mentioned in the incident https://support.mozilla.org/en-US/questions/1142103.

With 108.0.1 how can this be implemented like in the past versions? Thanks

Specifically I cannot access the PG&E website. FF is suddenly unable to bring up my login page. Several versions ago I started having trouble with another webpage where I webcam is updated every 5 minutes. All other browsers work for these two websites (Edge, Chrome and Brave).

I used to be able to press Enter in the empty Firefox search bar to bring up the (DuckDuckGo) search page and enter my search from there. Don't ask me why I like doing that, but now after the latest Firefox update, 128.0, on my MacBook Air I can't do that anymore. I have to type in the search bar to bring up the search page.

I know it's a small thing but I wonder if it can be put back to the way it used to be.

Hello,

Couple of days ago I could not start up Mozilla Firefox due to a corrupted file. Naturally, I was immediately worried about my bookmarks, extensions, browse history...

In the end I re-installed Mozilla Firefox -without removing my old folders on C-drive and in AppData- and was able to recover my old bookmarks and extensions just fine.

However, for my old browse history I am not so sure. I have not found a way to restore those.

Could someone help?

Thank you in advance!

Firefox releases email addresses and our data to third parties!

I installed the Arc browser and Arc offered to load my bookmarks from mozilla. Out of curiosity, I let it, and it loaded my bookmarks and folders smoothly. Arc didn't navigate Firefox to the login page, so Firefox released my information without asking me.

What probably happened in the background was that the Arc browser told Firefox which email address it was requesting data from, and Firefox handed over the data to it "on notice". Firefox was not even convinced that the real owner of the email address asked the Arc browser to synchronize the folders.

Is it the famous Firefox reliability?

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Hiya,

I use a theme which some years ago (after a change in the way Firefox handles dark-mode preferences) changed all UI and websites to use dark-mode. I was able to keep using the theme, and mostly override this behavior by setting:

`layout.css.prefers-color-scheme.content-override = 1`

However, this didn't take for some components, such as the sidebar and bookmark editor window, which still continue to use dark-mode.

Is there any way to completely disable dark-mode everywhere, and still use my preferred theme?

Cheers, Afraz
