Firefox Support Forum

I have four browsers on my Linux box: Chrome, Chromium, Thorium, and Firefox.

Firefox is painfully slow using Google Earth, all the others are fast with Google Earth.

This is fairly recent behavior (last month or so).

As far as I can tell, FF is configured to allow Web Assembly (WASM) to be used for rendering images, etc. Since Google Earth is written in WASM, I don't have a clue why it is so horribly slow.

scrolling/sliding the image around on the screen is slow and jumpy. Displaying images attached to a waypoint is extremely slow: It takes 5-10 seconds to switch from one image to the next.

Any suggestions? Thanks in advance!

Hi. i ran into a broken problem. sometimes when i bootup my pc and start the firefox, My windows crashes immediately. what shuld i do and how i can send the firefox log files to mozilla team?

alright guys you need to fix your browser, it crashes everytime i try to play a youtube video.. i searched tou site for fixes and NOTHING worked. you vanilla version of the browser was perfect then yall had to go and do the microsux thing and screw it all up by adding this that or the kitchen sink. i have submitted numerous reports yet no resolution. if you guys dont fix your crap i will move on to another browser and recommend to all my friends n family to do the same.

For about a couple of weeks, there has been a lot of delay between what I type and when it actually appears. It's maddening! I have not changed any of my Firefox settings. I did a 'refresh' about an hour ago. I am not seeing any network activity that I cannot recognize. I d/l'd 'Malwarebytes' and ran it..."no threats". MS Defender has always been on & protecting me. I have never had this situation occur before and am hoping for some help (5 to 10 seconds to wait for what you've keyed in is not fun).

Settings > Home > New Windows and Tabs > Homepage and new windows

This setting got reset on me last night. Using 127.0.2.

So, I set it to custom, add in a URL, close the settings, re-open the settings and see it is set.

I close my non-pinned tabs and then close the browser.

Upon opening the browser, I am greeted with an empty tab and the Setting has reverted to "Blank Page".

I am using Linux Mint with Firefox 127.0.2 (64-Bit)

In Preferences Applications, setting

 CSV-Dokument      to    open with firefox

opens edless new firefox Tabs - so I had to kill firefox. (setting CSV-Dokument to open with OpenOffice works fine. But this is not what I want.)

In Preferences Applications, I found further CSV types: application/csv-Typ CSV Document (application/text) CSV Document (octet/stream) CSV Document (application/x-download) Which applications should I use for them ?

I found the file "mimeTypes.rdf". However, I am not familiar with the syntax.

In an earlier version I set it up so that opening a tab opened about:blank and the title was blank via a simple Greasemonkey script:

// ==UserScript== // @name blank // @grant none // @include about:blank // ==/UserScript==

document.title = "\u2800";

Now not only did Firefox restrict what could be set on opening a blank tab, (which required me to install an add-on), the Greasemonkey script doesn't work on about:blank anymore.

NOT to remove personal data? Does it give you an option for personal date not to be removed?? what about all the stored password? Can one of you tell me why all of sudden I get this error COULDN'T LOAD XPCOM? can you send me a link where to reinstall new version on top of the one I have running now Thanks

Hi!

I've been having consistent trouble getting firefox to save my passwords. I'm signed in, have all the password-managing options enabled, and I import my passwords from chrome (which I've wanted to stop using) but my saved passwords tab is always empty. The next time I use firefox and I'm logged out, it's all wiped clean. When I try to synchronize my settings and passwords after importing again, nothing happens when I click Synchronize.

I've restarted the browser many times, opened it in Troubleshoot Mode (here I was able to import, save my passwords and synchronize just fine), went on to disable all my extensions one by one, themes, and hardware acceleration, but when I opened the browser normally, the problem persisted. I don't know what to do at this point!

I'd appreciate some help, thank you.

Problem: When exporting or downloading content from the GUI in the digital forensics tool Velociraptor, underscores are appended to the beginning and end of filenames. File is otherwise downloaded correctly, but removal of underscores necessary if original filename is desired. One hypothesis is that perhaps for security reasons there were changes made in Firefox 127 for how character escaping is performed.

Tested Operating Systems: Ubuntu 24.04, Windows 11 22H2, Windows 11 24H2, macOS Sonoma (14.5) Affected Firefox version(s): Confirmed 127.0, 127.0.1, 127.0.2 Tested Firefox versions which do not reproduce the behavior: 126.x, 125.x > Testing Microsoft Edge, Chromium, Google Chrome on Windows, macOS, Linux: files download with correct name as expected. Testing performed with clean installations on clean VMs with no add-ons enabled.

To reproduce: Download the latest release of Velociraptor from Github (at the time of this writing, 0.72.3) for preferred platform / operating system. Run Velociraptor using the gui switch, e.g. "$sudo velociraptor-v0.72.3-windows-amd64 gui" or "$ velociraptor-v0.72.3-windows-amd64.exe gui" Navigate to Server Artifacts and click the "+" icon at the top Search for Server.Utils.CreateMSI - select and press Launch Select the newly-created flow, click "Uploaded Files" tab and click vfs_path to download the file or, click the Notebook tab and click Download JSON or Download CSV buttons to download JSON or CSV respectively, underscores are appended to beginning and end of filenames.

I use Firefox to access my bank account, and it autofills the personal id number, and, when I click, the 6 digit code, which I allow it to store, because no one else has access to this PC. BUT, I had to take it in for repair, and give them my Windows login details. When I got the computer back, I went to the bank login page, and the autofill was a different personal id number. Does this mean that somebody used Firefox on my machine to login to their account? Or could a reboot have meant that Firefox randomly changed the PID number? Thank-you for your help.

I have set Firefox to not automatically restore the previous session on launch. That is, "Open previous windows and tabs" is unchecked in the Startupsettings.

Most of the time it does not do so, however the previous session will get erroneously auto-restored in the folowing circumstances.

Open a few tabs in a normal Firefox window. Fully quit Firefox (via, for example, pressing ctrl+shift+Q). Open a private window first. Open a normal window second.

What should happen is that the new normal window contains just a single new tab. What actually happens is that the tabs that were open in the previous session get auto-restored in this normal window.

To sum up, there is no auto-session restore if Firefox is launched with a normal window first. There is auto-session restore if Firefox is launched with a private window first, and then a normal window is opened second.

Is this a known issue, and are there any known fixes to prevent the auto-session restore in the latter case also?

Hello, when in the library, pressing F6 is meant to "Focus Search Field". This is documented at https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly

However, since a recent update this no longer works. Instead, pressing F6 now switches the keyboard focus to the lefthand tree pane. A further press of shift+tab is needed to move to the search box.

My questions are: Has F6 stopped jumping to the library search box for anyone else? If so, was this a deliberate design choice? Does anyone know of an alternate keyboard shortcut to jump to the searchbox? Finally, is there anyway to revert to the old F6 behaviour?

Even if you can only answer the first question that would help, so I can determine whether or not it is just my Firefox. Although I have already tested in a brand new profile with the same results.

Thanks.
