Since about a week or so ago late October or early November 2020, Gmail will not load in Firefox.

I began having this problem about a week ago. Sometime in October or early November of 2020. Gmail will not load in Firefox. Clearing cookies and all cache, works one time. Then it starts all over. Resting also works, just once. This is a giant PITA. I have to reset or clear the cache every time I use Firefox or Gmail won't load. It works fine on all other browsers. If I want to use Firefox for Gmail, I have to reset it or clear it every time I start Firefox. I have to go back to Chrome to use my Gmail.

Dear Sir or Madam -

I installed Firefox version 84.0 on Friday, December 18th. Since that was done, when Firefox is first started after a Windows reboot, it causes the graphics driver to crash repeatedly. Each crash generates Display event 4101 (copied in below). Usually, after three crashes (sometimes more), Display event 4109 is generated (copied in below). At that point, Firefox is blocked from accessing the graphics hardware.

This condition prevents some webpages from functioning properly. An example of a page that did not function was an e-card from https://www.jacquielawson.com

I looked at this article - https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration

I followed the suggestion in the section titled "Search for and install new graphics drivers" , but no newer graphics driver was found.

Thank you for your assistance.

James Troy

Wow... I just updated and am trying to use Firefox as my default browser yet again, however, yet again, it's RAM usage is ruining an otherwise good relationship. Why does this browser guzzle RAM so hungrily? I had to reboot it as I couldn't type any longer, without waiting every few letters before seeing them on the screen, and I've got 60 Gigs of RAM. But Firefox was using 22 of them!

This has obviously been an ongoing issue for years, both from my experience, and the 2,000 threads that come up in response to this issue. Come on guys, it can't be this impossible to create a functional browser that is more RAM efficient, what's the problem?

Oh, and it sure would be nice, given 2,000 results from my search, to be able to filter them by date. I'm using version 84, so threads dealing with version 50 or so, aren't going to be of much help...

Sowas kompliziertes wie Firefox support habe ich in meinem leben noch nie gesehen. Es wird zeit sich von Firefox zu trennen. Ich musste mich jetzt anmelden um überhaupt hier etwas zu schreiben. Ob ich eine Antwort bekomme steht auf ein anderes blatt papier. IHR SEID SCHEIßE!!!!! Wenn mein gesamter PC noch mal wegen FirefoxUpdate runterfährt, schmeiß ich alle Mozilla produkte von meinem PC runter und nutze Microsoft Edge oder Chrome. Jetzt reichts. Euer SCHEIß Update könnt ihr euch selber verpassen. Jedes mal gehen meine ARbeiten verloren, weil Firefox sich oberste Prioritäten setzt den PC runter zu fahren. Das kann's nicht sein. Und um kontakt aufzunehmen mußte ich 30 klicks machen. Ich werde euch nicht mehr weiter empfehlen. Ich habe 8 PC's in meinem Haushalt und alle das selbe problem.

In MacOS Big Sur 11.1 on my MacBook, I have set MacOS to automatically switch between Light Mode and Dark Mode. But I notice that Firefox does not handle this well. When I have used my MacBook Dark Mode and switch back to Light Mode, Firefox still hangs in Dark Mode. The only way to solve this is to choose Light Mode in System Preferences instead of automatic.

So I've been experiencing a rather annoying bug/issue, and I have a work around for it, but I would love if anyone could help me figure out the issue at hand. I couldn't find a relevant, up to date solution for this issue.

Basically, certain websites (the most notable being Reddit) will eventually no longer load. In fact, it won't even try to load. I will click a link from a Google search, or even just type in the URL for Reddit directly, and Firefox just does nothing. No error, no loading, nothing. The tab will stay blank with the URL listed as the name of the tab. I can't seem to tell if other browsers have this issue as it requires a bit of use/time to pass, but it doesn't seem to be an issue in Explorer. It isn't JUST Reddit, but it's only a couple of sites that this occurs on.

I do have a workaround --- if I tell Firefox to "Forget This Website" - suddenly it will work again. I will be logged out and see the default page due to having deleted all saved dated - but the site will work (for maybe a day) before I have to forget it again.

If this was a once a month type issue it wouldn't be a big deal, but the fact that I have to constantly re-do my local settings because of this is frustrating.

I am running Windows 10 and my Firefox version is 85.0 (64-bit). I have tried disabling any add-ons such as my AdBlocker, however that does not fix the issue.

I wish to know how to fix this issue (magnet links) ? I've installed bittorrent, but not showing on d.a.s page, after refreshing Firefox. Error msg: This file does not have an app associated with it for performing this action. Please install an app or, if one is already installed, create an association in the Default Apps Settings page.

Since somewhere last autumn, when I download any file from any website, the browser vanishes without any warning on the moment I navigate to the destination folder.

I maintain 2 websites (Joomla), and last week both required uploading a few files in Phoca Download to make them available to members. Now also on this upload the browser was completely gone when I navigated to the folder where I kept the fles.

I use Firefox since about 1995. I looked in about:Crash (first time ever), there were to reports, both unsubmitted: 69990c58-1a5c-40a3-9141-666607416103 6/22/2020, 1:23 AM e6f0688e-73e4-4c19-8e0a-01ec3c28e996 2/22/2019, 4:09 PM I have submitted them both now.

When you are presented with a text field, sometimes when you type, a small list of words you entered previously will drop down. You can then select one of those previous words, or continue with what you were originally typing. This is the Autofill feature for Firefox.

Lately, it has been a pain. After an hour or so of use, the instant I click on a text field to type something (usually for searching), the autofill box would partially drop down, only for Firefox to completely hang up. Once you recover from the initial crash, the autofill bug would not appear until at least an hour later. I tried turning off Autofill, but it cost me access to my History, so I was forced to do a complete browser reset. This issue has been with me for about a couple of weeks, and I have no idea why it's doing this.

Latest update blocking website like indeed from loading in information about employers and other sites too. Every update makes firefox worse. I started using other browsers because now some video's don't work either. Last thing I saw was a QUICK pop-up that said something about bits of trackers now being blocked. Well lots of things are being blocked and making browsing a miserable experience. I tried using the standards system in options. Can't find anything to make it work. Allow lots of things and nothing is working except to probably make the web browser more vulnerable to creeps. Please undo your current update and stop making so many updates. I've had three in the last two weeks and every time they screw up the browser more and more. Just stop it!

I have had Firefox downloaded for a considerable amount of time and had begun to use it as my daily browser, until I started experiencing issues, concerning the loading. I have experienced this issue in all cases when trying to open the browser through the desktop shortcut, other icons, and even the .exe file, and typically I will see a brief white screen of Firefox before it immediately closes again. Frustrating to say the least and a quick google provides no insight. I have attempted on multiple occasions to uninstall and reinstall, however to no avail, and have even tried to create a new profile, via the Run (Firefox.exe -P) but again with no success. Running the browser in Safe Mode (Shift) will also work for a split second with the dialogue opening and then instantly shutting. Any suggestion on a potential fix would be great.

I loaded Firefox onto a new Win10 laptop yesterday and made it the default browser (against the "recommended" Edge). Today some websites are loading very slowly (e.g. PCMag home page takes 30 seconds to load). Some https sites load normally and others are slow. I refreshed Firefox, did not fix it. Is there something I can do?

Hello dear supporters,

Since a few Days I cannot reach any website. Or sometimes Websites Doesn’t load completely and get stucked. Or sometimes there is a reduced layout loading on the websites I want to go to _ more like in html mode.

different errores occur Browsing with Firefox:

SSL_ERROR_HANDSHAKE_FAILURE_ALERT SSL_ERROR_BAD_MAC_READ The wlan connection is stable - as in can Go in the Internet with other devices.

And the problem also occurs with other browers . Additional Info: (Also the Connection to the email servers communicates a problem with SSL: Failed to send the message. SSL has received an entry with invalid message authentication code. The settings for smtp.1and1.de must be corrected. ... then Every once in a while I can send messages )

Could you please help me to fix the problem with Firefox as I am in home office, like many of us, and working gets difficult like this.

Thank you Silvia

Hey,

on one of my notebooks (Thinkpad E495) FF occasionally crashes. This started happening a few months ago. Before I've been using FF on the same machine for years without any issues. It's pretty random but usually happens at least once a day, usually shortly after startup or wakeup from hibernate mode. A while ago it used to even crash back to back twice in a row meaning after I reopened it, it immediately closed again and only worked after I selected to restore the previous session after the 2nd reopen. Nothing is registered under about:crashes and I don't see any errors in the system event log.

I already tried to disable hardware acceleration and reinstalled FF completely without any addons besides a different adblocker. I cannot really reproduce the crash in safe-mode but don't really want to browse the web for possibly hours without an adblocker.

Any ideas what this could be or what else I could try? Maybe downgrade to a previous version?

This has been an issue of mine for the past few days and I can't find a fix. I've tried to troubleshoot it and I've repeatedly reinstalled Firefox several times. The application either:

a. Doesn't open at all after I click the icon b. Freezes, refuses to register inputs and/or crashes c. Works temporarily, eventually turns into part B

My OS is Windows 10 and I want Firefox to be my default browser but it's not running properly at all on my computer. I have sent multiple crash reports because of this. Does anyone know what the problem could be? This has never happened to me before.

I'm using a Surface Pro 7, running Win10H. Firefox had a brief period when I first installed it where the on screen keyboard would appear and work, that stopped after a few hours and has not worked since. I fiddled with the settings on both Firefox and my surface, though nothing has changed. Un/re-installing did not help, thought it could reset something. Any fixes or advice would be greatly appreciated.

For clarification, the Accessibility Menu on-screen keyboard does work, but the tablet-specific larger keyboard does not function. It does open and type in other applications.
