I just updated to FF 111.0. After restarting FF comes up but then nothing. After a bit of I got the option to force close it. I tried opening a Private Browser and that worked fine so I figured it was one of my add-ons. However after closing the Private Browser and trying opening normally again it worked just fine. Disable all of my add-ons and for the same issue.

Renamed my AppData/Roaming/Mozilla folder and starting as normal worked fine. What a giant pain in the <bleep> trying to set everything back up.

Performed some more science and noticed this. After setting my Mozilla folder back, starting FF, and looking at the TaskManager, There would be 3 processes, one of those after a bit of time would show in red as Not Responding (or words to that effect). Clicking the window a few times to get the force close dialog again. Trying to open FF again, it opened just fine.

So I'm tempted to blame something in the update that is causing this. Yes, I could just start with a fresh Mozilla folder and reinstall all of my add-ons and blah blah blah, but whose to say that after setting everything back up the way I had it the problem won't come back.

I have thought about rolling back to FF 110.0.1, and suppressing the update check.

OS: Windows 10 64-bit Firefox: 111.0 64-bit

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.

I realise that Firefox uses up a lot of Memory (particularly as it tries to run each Tab separately). However, my Firefox seems to keep increasing its usage!

I can start with a number of Tabs open & (after refreshing each Tab - to ensure it is "lice" & "active") I will get (according to Windows Task Manager) about 1,300MB in use.

Without opening up any more Tabs & without trying to run any Web-Based Videos, over a period of a few hours it will increase & increase & increase - perhaps getting up to 4,000MB!

I've cross checked with "about:performance" (to open FF's own Task Manager), to show the individual Tab usage, & that NEVER totals up to anywhere near the figures shown by the Windows Task Manager!!

Obviously, my FF is fully up to date!

Any comments!

I have classmates and co-workers who are trying to volunteer but would need an approved signature to sign on the volunteer document is that possible to get an E-Signiture on our document?

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 am continuing to have issues going to this web site. www.goldtonemusicgroup.com/goldtone. Works great on chrome but firefox fails miserably. The page needs to be downsized and when you click on a link it may open it but it may be behind it but I am never able to get to it. I think possibly the last update something must have messed up. I used to be able to load it but not anymore. I have to use another browser to work with this web site. Other web sites seem to be ok. Thanks for any info.

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.

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.

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 am constantly frustrated by unresponsive pages / script warnings etc using Firefox. This never used to happen on previous builds -- I am using the latest 86.0 -- but these occur so often that I am about to say goodbye to Firefox. This does not happen when I am using Chrome and other browsers.

I have been through all of the suggested steps to deal with these unresponsive script/page issues, and none has worked.

Would appreciate any help on this, but as I say I am about to leave Firefox at this point for Chrome and other browsers.

Thanks in advance...

Dear Community,

I have problem with my Firefox version 86.0 (64-bit). I have Windows 10 20H2 64-bit operating system. Firefox can't load some websites. For example I can load https://allegro.pl/ but I have problem sometimes with this website: https://allegro.pl/myaccount/newpayments_incoming.php

If you go there and use F5 key on keyboard (refresh website) sometimes this can't load. On other browser I don't have this issue. This very frustrated me because I can't work. On Windows 10 1909 on older machine (another computer) I don't have this issue with my firefox (this sam 86.0 version). So this is probably problem only with Windows 10 20H2.

Steps to reproduce:

1) Open new tab and go here: https://allegro.pl/myaccount/newpayments_incoming.php 2) Log in to your account for Allegro website (without account you can't load website) 3) When website loads normally you must refresh this website (F5 key on keyboard) few times (you must be patient, sometimes this can take some time) 4) When website can't load or it's load partly you can see that this stops loading when it try connect to analytics.google.com so I think that it is very strange behavior.

On other browsers on Windows 10 20H2 version this website works without issue. Only with Firefox I have a problem. On Windows 10 1909 version on another machine I can't notice this issue. Also on Ubuntu I don't have any problems with this website with firefox.

Can you fix it? I can't work on my computer with Windows 10 20H2 system. I musted to switch to another browsers (Google Chrome, Microsoft Edge). I contacted with owner of the website but this is not the first problem with Firefox on Windows 10 20H2 so you should fix it. I remember that I had some similar problems on another websites but I don't remember what was address for these websites.

Actual results:

Sometimes I can't load this website on Windows 10 20H2 64-bit: https://allegro.pl/myaccount/newpayments_incoming.php

When website can't load or it's load in a part you can see in the bottom of the browser that this stops when it try connect to analytics.google.com so it is very strange behavior.

This can be not problem only with this website.

Expected results:

I should load this website always: https://allegro.pl/myaccount/newpayments_incoming.php

I hope that you can fix it.

hello there and good evening:3 my husband and i are having this repetitive and extremely frequent bright yellow pop up with a robot that states "a webpage might be slowing down your browser." then the option to wait, or stop it. i've ran out of patience with this notification to the point to where even though i'de hate to, i would have no choice but to switch back to chrome just to stop being spammed by this pop up while im trying to relax. it happens more frequently on youtube and walmart.com, and i just want it to stop because it seems as if when it does show up, once it starts it never stops, and it actually slows down my webpage to the point of becoming unresponsive and stalling/crashing my only webpage open at the time. my husband has the same issue and we both use windows desktop. it only started appearing after the latest update. please, can someone help me make this thing go away? its very stressful and i cant browse in peace anymore on firefox. yes we have turned off all background processes, and we both have scowered settings troubleshooting for hours at a time to no avail, it just never stops and it behaving like a really bad bug.

On old tabs, where I have opened google.com, there is infinite captcha! Once I solve it, it will immediately return back. I tried delete cache and cookies and restart PC. Nothing helped! I read on reddit it is known issue with Firefox!

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.

Hello, I am a screenreader user and since updating to Firefox 86.0.1 (64-bit) I have encountered a serious bug on Netflix that is very easy to reproduce, even for those who don't normally use screenreaders. Serious in the sense of making the site unusable once it hits. It happens with both the screenreaders I use, Windows Narrator and Non-Visual Desktop Access (NVDA).

Basically on Netflix if you do something to cause an informational alert (such as adding a film to your list), then this alert is read out over and over, indefinitely. You then can't hear anything else such as a plot synopsis, or if you move to a different button, you won't hear information about what button it is, as the screenreader just keeps re-stating the same alert. The looped alert keeps playing even after you start watching a film or show. As I say, the site becomes unusable. Whereas in older versions of FF such alerts would be read just once and that was it.

To reproduce: Start a screenreader (the built-in Windows Narrator can be toggled on and off with ctrl+win+enter). Go to the Netflix website (you may need an account and to be logged in). Pick any film or series tile, and do something like press the 'add or remove the item from your list' button. Or press it's 'rate thumbs up / down' button.

You will now hear something along the lines of 'alert: item was added to your list' repeated over and over.

Another example is to start watching a show with a skippable intro (such as Homeland for example). You will hear 'alert: press the S key to skip the intro' repeatedly.

As I say above, in older FF such alerts were read out just once.

So, is this a known issue? Thanks for reading.

Hi,

I think I broke the ALT keyup events in some way, probably with my configuration but not sure how.

If I put this code in the console : `document.addEventListener("keyup", e=>console.log('alt: '+e.altKey+' | '+String.fromCharCode(e.which).toLowerCase()));` and the press the keys, I have the following results:

- pressing "I", I get the expected "alt: false | i" - pressing "ALT+I", I get "alt: true | �"

I do not have the problem with other modifier keys like CTRL
