Firefox Support Forum

Running Firefox on MacOS. Browser will occasionally delete previous session when re-opening the browser. I do NOT have the browser set to clear history on closing. I have noticed that two of the incidents occurred when I accidentally closed the default window that opened when restarting the browser but I still had Firefox open.

Really frustrating when I lose all my open tabs with research I was conducting for work.

I just started getting "403 Forbidden" when trying to access dexterlive.com from Firefox running on a Windows 7 PC. It's been working for the last 5 years. I tried with Chrome. It works fine. It also works fine on Firefox running on my Android phone. What's happened to Firefox on the PC?

I had to switch to a new Windows 11 laptop. I installed firefox my favorite browser. It has been a disaster. after 1 week of trying different settings I have been unable to log into Facebook, Ally Bank, Netflix and others. I have changed the delegated credentials from true to false and it doesn't work at either setting. I am either getting SSL errors, "Pardon the Interruption" on netflix and some sites just say "Unable to log you on". Please note that I can successfully log on all the apps on Edge.

I cannot get the Firefox Browser Page to fit the screen on my laptop. I constantly have to hit <cntrl> - or + to zoom in and out. I have to do this for every tab I open. This isn't an issue with other browsers. I'm about fed up and ready to quit Firefox. I'm not "tech savvy" so if you respond use baby language. I'm operating on Windows 11.

I downloaded Last Pass through Firefox years ago...almost as soon as became available. The prompt for the Master Password does not function as it should but it does on Microsoft Edge. I've spoken with Last Pass on this and we added it to Edge in order to test the results. The result was that the Lass Pass icon on Edge remained lit but was not lit on Firefox. It should re-time itself whenever Last Pass is utilized and I use it for all my log-ins throughout the day...every day! I do not like Edge and use Firefox exclusively. I find this situation extremely disconcerting. I've been asked to enter that Master Password again and again within the 24 hour re-prompt schedule...at times within minutes! This should not occur. Please fix this glitch. It's between you or your developer and Lass Pass. It has nothing to do with me

Hi there! I am a long time Chrome user and decided to try Mozilla Firefox. I loved it and after a bit of tweaking, I run into a problem I can't deal with myself. In Chrome I loved auto fill options every time I needed the option for my home address, email address or credit card. In Firefox I just can't do it. The option is only available for Canada or SUA. Is there any way I can make it work? Of course, I looked for some add-ons and actually found several, but given the fact that auto-fill in my case deals with personal and sensitive data, I need a safer method. Is there any? Thank you!

Just restarted PC and opened Firefox, but with my normal Firefox, another page popped up which was a Firefox guest page on the website:

moz-extension://42c45938-6520-42aa-9359-a19de1 12eaf2/js/common /indexhtmizcontentType=notify_shutdown_ti#entry=sync

The website was "Not Secure" so I just closed out of it, was wondering if this is a cause for worry or if it's just a minor issue. All help is appreciated, thanks.

Problem logging into several sites with Firefox but no problem with Chrome or Edge. Firefox is and has been my browser of chose forever and I really need a fix for this

I've run into a troublesome error with Firefox for probably eight months now, so I have not been using the browser. Whenever I attempt to install ANY add-on from the Firefox add-ons page, I get the message "[Add-on name] could not be installed because Firefox could not modify the needed file". Furthermore, attempting to download the add-on file manually (should it be available on a github page or the like) leads to the same message or a notification that the download failed.

As a matter of fact, downloading almost any kind of file on Firefox inevitably fails. The exact notification is shown in the upper-right corner of the browser window, where downloads are shown, and beneath the file in question is an indicator that says "Failed". Everything from .png to .zip to .exe appears in the downloads queue for a second, then fails.

I have tried every solution the Firefox add-on troubleshooting page has suggested, including solutions suggested in other threads, such as deleting/creating new profiles. I have also attempted to completely reinstall Firefox on multiple occasions, as well as the refresh Firefox option.

To recount, the following troubleshoot solutions did not work:

--Everything on the Firefox add-on troubleshooting page --Restart Firefox --Refresh Firefox --Create new Firefox profile and attempt to install add-ons from there --Delete and renew the extensions* files from the profile root folder --Modifying the xpinstall.signatures.required in about:config (true or false, doesn't matter) --Modifying the extensions.alwaysUnpack in about:config (again, true or false, doesn't matter) --Double-checking allow list and permissions on local firewall and antivirus software (the app is protected, add-ons are allowed) --Disabling antivirus software --Running Firefox as Administrator --Reinstall Firefox --Restarting PC

If I want to download a file or add an extension, I need to switch to a different browser such as a chromium-based one or Microsoft Edge to download the file. In the case of add-ons, I switch browsers, download the file, and select the "install add-on from file" option under "manage extensions" in about:addons.

One final thing. It seems that sometimes streaming sites won't work on Firefox (even with ad-blocker disabled or the site allowed through the ad-blocker), and sometimes video won't properly load either. These things work fine on other browsers.

I really like Firefox as a browser and enjoy the privacy it provides built-in. I didn't have any of these issues up until last year and I was forced to switch over. I would really appreciate any help with this.

Entire set of subtitles being shown at the start of the video and then nothing. For e.g. try this link: https://www.youtube.com/watch?v=kvN5_GXlg2Y

Please let me know am I the only one or what? Also issue is not occurring in incognito mode which could mean I just need to clear some cache.

My browser has beenc rashing all day. I have not isntalled a new add on, nor removed an old one, I havent made an update or anything.

Anybody experiencing something similar?

System: Mac Ventura, latest ios firefox: Version 114.0.1

Received SSL error code: SSL_ERROR_RX_MALFORMED_HANDSHAKE when attempting to communicate with JetBlue.com. JetBlue claims issue is with Firefox on my computer. When I go thru Google Chrome, I can communicate successfully with JetBlue with no error issues. I tried using your self-help screens, but find them of no benefit in resolving my problem. Regards, Richard.

Before the latest update, I was able to open links (eg zoommtg:) but that quit working. I originally thought it was a problem with Ubuntu, but I tried in Chromium and it seemed to work fine. In addition to not being able to open links, I can't click on the "Show Folder" in the downloads dialog. This leads me to believe Firefox is having trouble communicating with the desktop.

• OS Ubuntu 22.04.2 LTS
• Firefox Version 114.0.1 (Snap)

Ideally, I'd like to find a log or some indicator as to why this is happening. It's quite annoying because I find myself doing a lot of copying and pasting of links and what not. Any help would be appreciated.
