The behavior began with fifteen to twenty crash messages appearing. After which the browser would stop responding and be unable to reach out to the internet.

Network connectivity was confirmed as I was able to access my VPN and corporate teams.

I submitted as many crash reports as I could. Eventually the crash reporter ceased to function. The message is:

Firefox had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash.

Details: expected value at line 1 column 1

Only a full reboot of the machine restored functionality but only temporarily. It returns after being put into sleep mode.

Running firefox in safe mode does not restore functionality. The behavior persists.

I am fully up to date according to firefox.

I am running a Lenovo Thinkpad Windows 11.

when I sign into Goog/setting/2 step, the page does not show "app passwords." I've turned off my ad-blocker extensions and pop-up blocker on the page. See attached.

I have recently been getting an error message when I open Firefox saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". This has been happening since I clicked on a mail in Mail to unsubscribe from a spam/phishing mail list, which seemed to result in me installing Firefox Private Browsing, which I had never subscribed to. I have tried uninstalling Private Browsing but there is no way of doing that. I have even uninstalled and then re-installed Firefox completely but I still have the same problem. Because of the problem I have now lost all my bookmarks and history, and am unable to create new bookmarks and history. I have been on the help forums and seen that I can Disable Private Browsing by going through my anti-virus (Avast), which I have not yet tried because what I would really like to achieve is uninstalling and not having Private Browsing on my Start menu, rather than simply disabling it. Anyway, would disabling it solve the bookmarks and history problem ? Can anyone give me the solution ? Thanks. As you may gather, I am not very techno so you would have to give me the idiot's version of any instructions or advice.

hard drive failed on windows 10 pc, new drive put in & window 10 reinstalled with Edge browser (by experts) What do i do to get firefox browser as my main browser back with all my bookmarks etc & firefox VPN ?

Do I just download firefox installer & sign on & all bookmarks etc will be there?

Thank you for your help, Tony

Mein Laptop reagiert nicht, wenn ich mich über lockout abmelden will. Mir wird stets die Seite "Fehler: Gesicherte Verbindung Fehlgeschlagen." und nicht wie vormals beim öffnen des Laptops. Wo liegt der Fehler?

For the last few weeks i've noticed youtube vids buffer but then sometimes stop and when the video reaches that point on the bar it skips about 5-10 seconds, then contines to buffer like normal, so I have to use the arrow keys to go back to see what I missed. It is very annoying. Happens almost 1-2 every day at random times. My wifi speed is good. I've cleared cookies and caches, turned off enhanced tracking protection for youtube, i've even increased perfomance settings for intel graphics in my pc's power manegment plan. Nothing! Can anyone help, thanks.

When i scroll up and down on a page, it instead provides the back-page instead of scrolling up and down on the website. this is for all websites. the scroll function works oroperly in system settings, it is only with firefox. autoscrolling is enabled in settings.

There are a bunch of obsolete suggestions on opening FF without address bar, menu bar, etc., and kiosk mode.

I do not want Kiosk mode, but do need ability to open it via command line so that only the title bar (and borders around the app.

The most current available entry on the matter in the Mozilla site no longer works (at least for me) --

firefox.exe" -ssb https://www.example-site.html/

Also even if it did, not viable to update all FF users as these are customers, and they won't, simple as that. Chromium browsers just work by passing the command by default.

This is for use to launch a local help/users guide from a Windows application. Can do so on Chrome/Edge, but leaving out FF is less than ideal.

Hi Team,

Just installed latest version of Firefox - and cannot login into the browser to enable applications menu.

I can login into my Mozilla account but how do you login to this new version of the browser?

Appreciate your assistance

Michael

This requires some explanation.

I have 6GB of RAM, and am running Windows 7 64b.

I just updated to v115 from v56esr. I was using an extension that broke when the quantum update came out, and I wasn't willing to let go of it so I stopped updates. When the occasional website stopped working on the old version I would use Chrome for that website, but Firefox has always been my preference. Chrome was such a memory hog that I couldn't have more than a dozen tabs open at once before it crashed, and for me that is unacceptable. At this point however, enough websites have ceased to function in Firefox that it was worth it to me to update. After updating I found that Firefox uses just as much memory as Chrome. Where I previously could have 30 or 40 tabs loaded at once before running out of memory, now I only get about a dozen.

Question: In what version(s) did the memory consumption drastically change? What version can I revert to in order to bring memory consumption back to a manageable level? What other settings can I tweak to reduce memory usage? (For example, can I automatically reject loading of subframes?)

Please Note: - I use adBlock+ and I have made a habit of turning off tracking and rejecting cookies and notifications everywhere I go online to prevent excess resource usage, among other things. - I use very few extensions so there isn't really any memory to save there. - I understand that my computer is old and should be upgraded. Telling me to get a new computer or add more RAM is unhelpful and will not be appreciated. - I also understand that running out of date software is a security risk and is not recommended. I don't care, so don't bring that up. - And I also understand that I am a tab hoarder. Because of the way I work I typically have 50-100 tabs open, but I periodically close it so as to unload everything and usually don't have more than about 30 active tabs at once. - I know that some websites (particularly those with lots of subframes) use much more than other sites so my memory usage is entirely dependent on which sites I have open, and I know that I can open the task manager to close/unload unnecessary tabs and subframes. Having to do that frequently is a pain, and it doesn't work if I need all the tabs that are active.

Hi, I posted this question about 3 upgrades ago. I run Win7_64 (Yes I know it's outdated!) with dual monitors. After closing FF I was always left with a partial FF screen window open on the left monitor. It could only be cleared with a screen refresh, or dragging another app. screen over the top. I checked the obvious like GFX drivers (which had never changed), FF .exe processes seem to have terminated and I confirmed no other app did this (even Chrome). I suspected it was a FF shutdown problem? I asked the question here but didn't get a solution until now.

I've now installed the latest update 115.11.Oesr (64 bit) and have not seen the same problem for a week. If it stays that way, thanks to the FF team for fixing this annoying problem.

I'm on OSX Catalina 10.15.7 and all of a sudden I am unable to get any sound from my FireFox browser. I tried to play audio/video from 3 different websites - Youtube, 123greeting.com and Gettr and while the video played, there was no audio coming out on any of the sites. I have no problems watching and hearing videos on my other browsers - Brave and Vivildi so this issue is with Firefox on multiple websites. Please advise as to where to look for some switch to turn the sound back on my Firefox browser. Thanks

Hello,

I am trying to login to my Mozilla account so that I can backup my data and move it onto a new computer. However, even though Sync is activated, I cannot find my Mozilla Firefox password anywhere and am unsure of what it is. Is there anyway that someone who works at Mozilla can give me access to my password?

I am happy to verify my identity and prove that this is indeed my account, but I am not sure of how to go about doing so. I really need access to all of my data, and would be highly thankful for any assistance regarding this matter.

As per subject. When i click a Mailto link in a webpage, eMClient opens OK, but message window does not. Seems to be a Firefox problem because it works fine in Chrome. I've checked the Firefox and Windows (10) settings; all seems as it should be. Any suggestions? Thanks.

I often use Ctrl+Number to jump to a fixed tab, whereas on Linux the shortcut is Alt+Number, which causes some inconveniences. Is it possible to make Firefox use Ctrl+Number to switch tabs on Linux?
