Firefox Support Forum

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

I am trying to disable Firefox notifications whenever I take screenshots, and googling for solutions, I found the commonly suggested solution is to uncheck the "Pause notifications until Firefox restarts" box in Permissions:

How to turn off forever the "screenshot" splash notification

"shot Copied" window

This option is not available in my browser version; thus, I'm hoping there's a newer workaround for this.

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,

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've been using site https://mail.aol.com/webmail-std/en-us/suite for years to log in to AOL email for years and now, with Firefox v90, it takes over 2 minutes to load. It takes only a couple seconds with the Edge browser. I've tried troubleshooting mode, a refresh and a complete re-installation without any improvement. This never happened in previous versions of Firefox.

Any help is appreciated, Gary S.

I just installed the Firefox browser using the installer on the official website. When I attempt to open Firefox, even as administrator, the window either quickly opens and closes or doesn't open at all. I have no clue what is happening.

Firefox has WIFI stability issues. Chrome remains stable, but Firefox loses connectivity every 5 to 10 minutes. A refresh is required and often that does not solve the issue. A complete reboot of Firefox is required.

I moved my Firefox installation to a new machine. After creating a new profile and moving all my old files Firefox has opened with all of my old info and is operating properly.

But when I tried to change the location of the cache file to the correct drive on my new machine the about:config file does not save the new entry. When Firefox is closed and re-opened the new entry has been reset to the old location.

I've tried deleting the browser.cache.disk.parent_directory entry in about:config but when the program is re-opened the entry returns with the old directory shown.

Any advise would be appreciated.

Hope someone can help.

When I use full screen for some websites, it darkens after about 2 - 5 seconds and my cursor also becomes harder to move. This only started to happen recently.

It is not my computer settings, I've tested this in Safari and it works normally. This makes videos unwatchable. It is like a dark screen suddenly appears over the video and only comes off if i move the cursor. It happens with netflix and prime but not youtube, udemy.

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

I opened Firefox this morning, and was greeted by a new website. Very impressive! BUT I can't log in to my hotmail account!! the sign in page doesn't open at all!!! please advise!! thanks ... k

Hi all,

Since I switched to Win 10 Firefox constantly crash on my computer.

• Tried fresh install no change
• Tried repair no change
• Switched off extension and then on (one by one) no change
• Deleted cache - History - etc .. :( it worked for only a few days since I did a full scan with Microsoft Defender.
• Since this last crash (as I could not launch Firefox anymore I used shift + click on Mozilla shortcut)I decided to switch off the graphic card acceleration and all the other option in this menu and it seems to help

Could you tell me how to send you the crash report ( I do have 8-10 of them already sent to Mozilla)

Hi,

I'm developping a custom tool in order to automatically clean my cookies from several websites. For example, I would like to automatically remove cookies from twitter.com every time I launch my tool. I'm under Win10x64, firefox v89, tool developped in python.

To do this, once firefox is closed, my tool go in my profile folder, access to cookies.sqlite and delete row associated to twitter.com

-> DELETE from moz_cookies WHERE host == '.twitter.com';

The database is saved, no more "twitter" in my cookies.sqlite file, and the tool ensures there is no cookies.sqlite-wal or cookies.sqlite-shm files left.

After that, when I open again twitter, I am no longer connected to my session, but I got an error which seems to be related to cookies (see screenshot).

Moreover, when I oppenup the firefox cookies manager, there is still twitter cookies in the list, but 0 cookies associated.

Where is my mistake ? Can you help me solve my problem ? Thanks

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

Sir/Ma'am,

My system is a standard install, and when I open Firefox, click Help, About Firefox, and then click the linked word (Mozilla) "Firefox is designed by Mozilla" it takes me to "www firefox com cn" ?

Is the version of Firefox in the Linux repositories the China version with an American facelift?

I know you all do not have command and control of this, but I thought someone should be aware that the default Firefox browser for Linux installs seems to be the CCP Firefox and not American version. With all the CISA activity, it might be something to look into.

Kernel: 5.4.0-70-generic x86_64 GCC v: 9.3.0 Desktop: Cinnamon 4.6.7 Distro: Linux Mint 20 Ulyana Base: Ubuntu 20.04 focal

Firefox for Linux Mint: 87.0 (64-bit)

After update to 89.0 (or even after 88.0) tabs are constantly crashing. OS: Windows 10 pro (19043.1023), last update KB5003214. Firefox completely re-installed 2 times, last time with full refresh. No addons/extensions are in use, only default H264 plugin. Strict tracking protection with always "do not track" is set, but previously no troubles at all for years. Nvidia graphics driver last (462.59 studio) installed with EVGA GTX 1060. Hardware acceleration is disabled. Still multiple tab crashes. last crashes reason: "EXCEPTION_ACCESS_VIOLATION_READ" last crashes (submitted): bp-3b613b8c-4f74-460c-831b-541840210607 bp-7f8192e7-5720-4a53-99ec-8c7700210607 bp-fbe9f7bd-056f-429e-ad17-3dcc70210607 bp-ab56335a-970b-4b08-9b36-75d380210607 bp-8d21fb16-9911-4b84-af38-72d810210607 bp-0ac67369-165e-48ae-86ab-654e90210607 bp-81c77d11-e34b-40b5-83b2-37b850210607 bp-48ca4fc2-ccdf-4665-be60-bee740210607 bp-c8764a0c-285e-4c9e-ac7a-6ca910210607 Thank You for Your kind help. Denis.

it started from yesterday... when i open firefox after a minute or less the browser suddenly close all tabs and show me a report crash windows. . my windows specifications:

• Windows 10 Pro
• version: 1909
• OS Build: 18363.1440

browser: Firefox version 87.0 (64-bit)

I tried this options but didn't help me and crash didn't stop:

1. open it in safe mode.
2. refresh browser option.
3. disable and delete all extentions.
4. delete cookies and web data button.

. there is some information that i noticed. I unistall and install again and until I didn't sign in to my "firefox account" on the top right corner of the browser, it didn't crashed. but still I want my account, passwords, bookmarks, ect... i sign in and crash started. i goes to appdata and delete firefox folder, start the browser again, my sign in to firefox account disappeared and the browser stopped from crashing. also the crash happened immediately after hitting sync now and happened a few seconds after going to firefox account settings. and it's happening after around a minute when i do absolutely nothing after opening the browser or go to website such as youtube. please help me. even though using another browser is crash-free but i wish to stay using firefox (with my firefox account)

I have tried everything and cannot manage to load any webpage that prompts a reCAPTCHA. The tab immediately crashes.

1- I've tried several webpages. They all work well until a reCAPTCHA pops up, the tab crashes and creates a dump file 2- I tried uninstalling Firefox, including erasing profiles and all Mozilla folders then reinstalling, and selecting refresh. It sill happens. No addons or extensions, and HW acceleration on and off 3- The problems goes away if I run Firefox on Troubleshooting Mode

Version is 94.0.2 (64 bit) running on Windows 10 21H1 on an i7 1165G7

Am I missing something? Is there a way to do a cleaner install?

Thanks for the help!
