Hi All

So recently I had some windows issues on my newer laptop and had to resort to going back to my old laptop for the time being. Before using it I restored the system to factory settings and such then reinstalled the newest versions of firefox and such then imported my profiles that I backed up from the new system.

Was working fine for few weeks but the last week or so I have noticed firefox has become sluggish in how it loads websites and such.

I have tried setting up a test profile and that new profile was reacting the same way very sluggish in loading pages.

I have also cleared my browsers cache wondering if that would help.

I have also tested loading pages in Microsoft Edge to see if it was browser or system related and Edge seems to be loading pages just fine so it has to be browser specific.

Any ideas what I should try next to clear this up as the sluggishness is getting old fast!

Thanks

Hello,

I have a problem with login on a few selected sites. On some sites I cannot login at all, on other sites I can log in, but as soon as I don't interact with the website for a few seconds the login is lost and the next click on any link shows me a "not logged in"-state.

For example on my companies Outlook Web Access site, when I enter my account info and click on "Sign In", it briefly shows a loading screen and then takes me back to the login site. On another webiste I can log in and use the website without problems, but not clicking anything for more than ~5 seconds leads to the login being lost. The strange thing is: in incognito mode everything works fine on both sites!?

Firefox is 87.0, I have already deleted all cookies and stored data.

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.

Dear all,

I am planning a move towards the Firefox ESR 78.6.x. Currently my customer is using the Firefox Rapid Release 84.x and need your help with the profile migration. The customer has a very isolated on-premises environment and does not allow the users to login into a Firefox-Account. Therefore the settings for Cookies, Cache, History and especially Bookmarks are not synched.

Environment details:

• Enterprise environment with several tausends of clients
• All clients on Windows 10 Enterprise between 1809 and 20H2
• All clients have always the newest Firefox installed currently 84.x

This creates a huge challenge to sync this stuff. Therefore I have now identified the following two options:

1. 1 Allow the downgrade by using the environment variable MOZ_ALLOW_DOWNGRADE on Windows. For this option I am trying to find the real reason why this "Downgrade-Stop" has been implemented in the first place? What risks in detail do I take to allow this downgrade? Has anybody done this before and do you mind to share your experience here? How many issues did you face and how did you remediate the issues?

1. 2 Hand over the migration to the users. Copy their current profile to their desktop and ask them to import their bookmarks manually. Not preferred by users and I can't even blame them for.

Is there any other way to automatically sync the profiles from 84.x to ESR 78.6.x without user interaction?

Thanks in advance Amir

I had a different issue I came here for, but I discovered a very serious bug while I was writing my question, so I want to make sure this gets addressed first.

After writing my question, I clicked the "share data" button below. I got a message "We can't automatically get your browser's troubleshooting data, please try these manual steps. " Without thinking, I clicked the link to the "manual steps." Unfortunately, instead of opening a new tab, which would be the expected behavior, clicking the link took me off the get help form page (the page I'm on as I write this). What's worse, when I used the back button to return to the previous page, everything I'd written was gone. Obviously, the expected behavior would be to not take the user off the page in the first place, but if for some reason it did, to autosave the writing so it can be restored when the user returns.

This kind of bug used to be a lot more common in the early days, when I first started using the web, 25 years ago. I used to have a boilerplate describing the problem because I was sending reports of the bug so frequently. I've only encountered it twice, to my recollection, in the last 5 years. Firefox's website would have been one of the last places I'd ever expect to find a bug this glaring and elementary.

Thanks!

I am on Mac OS High Sierra Since about a week literally any Russian website I open just crashes Firefox immediately. I have tried to restart in Safe Mode and clear history - it didn't help. What is happening?! Using Chrome in the meantime (no crash there)

I have many tabs like 200-300. Firefox crashed today. I also have 4GB page file on top of that. Strange! After I restarted Firefox it was using only 6.8GB RAM. Perhaps memory leak. BTW if I have browser.cache.disk.enable set to false. Is page file still used?

Thanks for help.

I am getting a certification issue when trying to visit 2 specific sites which are some of the most visited sites in the web: https://www.google.com and https://www.youtube.com

The error it shows when trying to visit these 2 pages, is SEC_ERROR_UNKNOWN_ISSUER.

I have tried to troubleshoot it and follow the solutions recommended at: https://support.mozilla.org/en-US/kb/error-codes-secure-websites#w_the-error-occurs-on-multiple-secure-sites

however none of the solutions described in this guide worked to solve my problem.

In that guide, one of the suggested solutions is to scan my system for any malware. I used the following: Windows Defender Maleware Bytes AntiMalware Karpersky TDSSkiller however the results are all clean.

In the guide, it suggested that I check the clock as well. The system clock however is synchronized.

Last, I have resetted Firefox Profile but this didnt fix the issue either.

I shall note that the issue appeared yesterday and so far nothing helped fixing it. Not even the system restarts.

The issue about visiting these two sites, is limited only to Firefox.

I can access https://www.google.com and https://www.youtube.com without problems using Google Chrome and the Opera Browser.

Also, Google Mail and Google Translate work fine on Firefox. These two sites can be accessed with Firefox without causing any SEC_ERROR_UNKNOWN_ISSUER errors.

My tabs are constantly - several times a day, every day - crashing. I'm not watching any videos, I've tried a clean (deleted profile folder) install, and turning off hardware acceleration. It's not anything attached to my profile, as I sync with a 2nd computer that has zero crash issues.

My tabs are frequently crashing and some strange behaviors occur with firefox after these crashes (adblock failing to work until browser restart, browser going blank for a split second). My browser also occasionally crashes, and even more infrequently my entire computer will crash which usually happens after series of tabs crashing in a row. It may be a ram issue but I have no problems with any other programs on my computer so I doubt that.

Reviewed "Sheribee" earlier issue which apparently involved a VPN. I do not have a VPN but have tried several times in the past week to access IRS refund status site without success. I can get into irs.gov, but am unsuccessful in accessing the refund status site after entering required input data. The issue has occurred only this past week.

I'm unaware of IRS issues causing this problem.

Have not had this issue on any other sites; and I have successful retrieved data in prior years.

I am not saving any sign on protocols with the irs or any other sites.

Running Windows 10. Thanks for any help. BTW I did get refund information using the telephone, but I want to ensure there's not a hidden conflict of some sort with FireFox. Thanks for any help.

I'm seeing some weird behavior in FF.

I have an HTML page that allows the user to click on a link to trigger a file upload to a remote server. The file being uploaded is usually > 2GB and takes a LONG time to upload (sometimes > 1.5hrs due to slow link to remote server).

What we see is the remote server ends up with multiple corrupted versions of the same file.

Could it be that FF is silently timing out waiting for a HTTP response and then retrying to upload the file? I can't think of any other explanation for the multiple files, since the user only clicks once on the hyperlink.

Thank you, Dan

When I try to use a platform like Netflix i get repeated error messages that WidevineCdm has crashed. This happens also in other browsers. I am not very tech savvy, but I've tried all the solutions I was able to understand on here and through Google, but nothing seems to fix the problem. Can any one advise?

Not sure if this helps, but here is one of the many crash reports I've sent: https://crash-stats.mozilla.org/report/index/75e61622-4282-4a83-b86e-9861a0210422

Thanks to terrible, productivity-sucking changes in the basic functions of the FF browser, I have started using other browsers. First - FF updates far too frequently - almost daily. No option to block update notifications. Never know if it's something trivial, an important security fix, or a major interface change. The 'what's new' page is always incomplete. 2nd - FF downloads software surreptiously through the sneaky "normandy" back door and inserts feature changes irregardlessly. Doesn't matter if you explicitly selected NO to enrolling in studies. Users can't get a straight answer on how to disable Normandy. Named after the Allied stealth invasion of Europe, it does the same thing to our computers. 3rd- FF caters to fringe techie desires with an onslaught of unwanted or unsuable additions that bloats the software, uses up CPU, or inserts intrusive attention-seeking diversions. I am forced to spend too much time after each update to investigate how to shut off unwanted surprises as well as unannounced alterations to my option settings. For example, if I press the mute button on my keyboard a very large media window pops up and takes over a sizeable chunk of my computer screen. It cannot be resized. It has no close button. Took hours to find out how to disable this. 4th-FF developers seem to expect users to have the newest computer equipment, huge display screens, and lot's of extra memory. If not, too bad. 5th - the recent puzzling, arrogant changes to the basic print function is evidence of that mindset. FF developers say they aren't going to let users revert to the normal "classic" small foot-print pulldown menu on the left side of the screen to preview, set up headers, etc. Too bad if the open window is too narrow to view this new intrusive, real estate consuming right hand display. Too bad that you can no longer simply seamlessly interact and accomplish the task. Too bad that the FF developers think they know better than you that you should change the way you work. 6th Reader view is an obscure feature. I do not want to be forced to use it. I do my best to strip out or ignore the overwhelming number of pictographs competing for my attention, 7th - I can no longer see URLs in the address bar. You've truncated them. I am forced to cut and paste them into a text editor to see them in their entirety. 8th - Firefox hangs video streaming sites like peacocktv.com. Windows Taskmanager shows that FF forces CPU and hard drive usage to 100%. 9th -There is no mechanism to escape, break, or interrupt FF's failed video stream. How sad that Microsoft's obnoxious Edge browser is better at video streaming. It uses far less system resources on the same video streaming site. AND doesn't hang the OS. It's likely FF's new unwanted capability to launch multiple picture in pictures - which I don't use - hogs resources. 10th- How about beta testing using 'normal' non-super techie /gamer users? 11th -FF disabled user Feedback. I stopped updating Firefox. Not trustworthy.

I have suddenly started to experience a TAB crash in FireFox when browsing in private browsing mode. The crash happens on a specific page, and occurs almost 100% of the time.

I'm developing a web application, and I want to view the application in private mode as I switch between QA, PreProd and local development environments.

I have not yet experienced the issue in normal mode.

Hi all,

I'm having a repeat of this issue: https://support.mozilla.org/en-US/questions/1291551

Again some links from emails have been giving me the "Warning: Potential Security Risk Ahead" page with the error message "SSL_ERROR_BAD_CERT_DOMAIN". I get this in safe mode but not in private browsing. I have tried all of the fixes suggested last time I asked about this problem including deleting cert9.db but that hasn't worked this time (so maybe it wasn't the fix last time either).

To be explicit, I've tried all fixes on these pages so please don't suggest them again without providing an explanation about why you think it will work (a technical explanation please): https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can https://support.mozilla.org/en-US/kb/firefox-and-other-browsers-cant-load-websites https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message https://support.mozilla.org/en-US/kb/connection-untrusted-error-message http://kb.mozillazine.org/Error_loading_websites https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors

Hello, since a few month the browser is shutting unexpectedly every couple of hours and all settings like starting page or prefered search engine are lost. There is no error message or error report. I'm using lates MAC OS and Firefox version (it happened also with the last couple of versions)

Some time ago, firefox stopped launching. I tried everything. I refreshed, reinstalled, clean reinstalled, reset windows, deleted possibly interfering programs, and clean reinstalled windows (that was for other problems). I am running windows 10 home build 10.0.19042 (currently the latest) on a omen HP laptop 15-dc0xxx. It is x64 bit device with a intel core i7 8 gen cpu and a nvidia 1050 ti mobile. It does not seem to be a hardware issue as a linux kernel that I have dual booting with windows 10 runs it like a champ.

    When launched the application load for a period of ~7 seconds and for a frame or two there is a small window with either nothing on it or a safe mode window that goes away after a frame. When the problems started I closed firefox and reopened it a small bit later and the problems above happened. Windows safe mode will run firefox. Opera has very similar problems if that helps any. Google chrome, microsoft edge, microsoft internet explorer are all unaffected.
