I have fedora 36 Linux on my laptop and I have installed Firefox from the software store. The version in Help>About>About Firefox shows 99.0.1 (64-bit).

I am able to play videos on Youtube but no video or GIF is playing on Twitter/Reddit/Facebook.

I have installed media codecs as per this fedora help

My autoplay setting look like as per the attached image. I do not have any extensions except Bitwarden on Firefox.

I also tried playing videos on Firefox 100 by downloading it directly from firefox website but faced the same issue.

From time to time I get an Error Overflow message in Firefox. Sometimes I enter the website directly in the address line and other times I click a link in an email and it tries to open in Firefox as it is my default browser. If I copy the address line to Chrome it loads correctly.

This is mildly irritating as it puzzles me each time it happens.

I have attached a screen snip showing the error.

Hi, yesterday I got a new computer and I installed the Firefox on it, but when I started the browser for the first time, it was a mistake (I pushed the button by accident), so I immediately closed it. It was asking something about allowing the use of coolkies, but I didn't answer to that and simply closed the window.

The thing is that since then my firefox don't load properly. The buttons and the autocomplete are normally responding, but all pages (including the settings) are blank and sometimes it won't start at all and I have to close it with taskmanager to make it open next time (but still blank).

Does anyone have the idea what's going on?

Thank you.

Hi, I have an existing installation of Thunderbird 91.9.1 on my linux system. I have a gmail, outlook and web.de mail each running via this installation (IMAP). My new workmail is hosted by 1&1(ionos). I can log in via web interface. Autoconfig finds the configuration that is (according to their help articles) the correct one to access the Mail via IMAP. Incoming: imap.1und1.de SSL/TLS 993 Outgoing: smtp.1und1.de STARTTLS 587 normal Password Username is my full email address. There have been no typos. I checked 5x, copy pasted, rechecked. Pasted it into the web interface login, and thunderbird before clicking go on each -> tb - no, web - yes domain is talsen.team

I would appreciate some pointers to get this fixed. And yes i did read prior questions regarding this error. It did not help in my case.

I am trying to open one of my bookmarks and it sits and spins for a long time then a message comes up that I am running an outdated browser and it needs to be updated to support their site.  ??? But I think I have the latest update.

I have lost my IMAP and SMTP connections between Thunderbird v91.9.0 on Windows 10 and two Gmail accounts. One is a standard @gmail.com account and the other is an @my_domain account on Google Workspace. The experience is (almost) the same on both.

Any help would be greatly appreciated.

When I try to read IMAP mail through Thunderbird, I'm presented with a pop-up (apparently from Google) to log into the gmail account with the email address pre-populated in the "Enter your email" field. Curiously, the email address for the Google Workspace account is broken into two parts with the user name left justified in the field, the @my_domain right justified and a gap between them. This is not true for the standard @gmail.com account, where the field is prepopulated with a left justified username@gmail.com. I click the "Next" button and an "Enter your password pop-up (apparently from Google) appears, into which I enter the password and click "Next".

Then I see a pop-up (apparently from Google) which says "Mozilla Thunderbird Email wants to access your Google Account", with "Allow" and "Cancel" buttons. I click "Allow" and often (but not always) see a small pop-up (apparently from Thunderbird) which says "Authentication failure while connecting to server imap.gmail.com".

The experience on the sending side through SMTP is similar. Upon clicking "Send" in Thunderbird, I'm presented with the same sequence of pop-ups (apparently from Google) to enter Google user name, password and permission to allow Thunderbird to access my email. Then there is a "sending message" pop-up (apparently from Thunderbird) which never completes.

Here are what I think are the relevant Thunderbird settings --

After firefox update to 100.0 - i can't use any of my addons, and cant install new one. All my current updates appears in "disabled" status, and there's no "enable" button. I have many addons, so it's the global problem.

Also, i can't install any of updates from addons.mozilla.org, i get message "Installation aborted because the add-on appears to be corrupt". All addon xpi files are downloaded without problem using "save as", also, after clicking "install" on addons website i see download progress.

Please help to resolve this issue!

Hi - I'm currently working abroad as a photographer, and am having great difficulty uploading image files larger than about 25mb. Is there a Firefox limit on files larger than this, or is there a setting I can use to allow larger uploads? Thanks, Alex

I have an ASUSStore where firefox is managed by them and is at Firefox 95.0.0.r1 The localhost page shows Boxes with the unicode codes in them - Firefox on a PC to the IP address of the box works ok

I also found that some internet pages work (display english text) and some do not - I have logged a ticvket with ASUS but is anyone able to see an obvious difference between the following URLS These URLs were on the on the Firefox startup screen default webpage Note that Show source of all these pages only shows boxes with numbers in them as well so I can't clearly see on the ASUS what the difference is

The following did not work

   https://www.amazon.com?tag=admarketdeskt-22<tracking>...

but I tried https://www.amazon.com?tag=admarketdesk and this was fine - so then I refreshed the full URL with the tracking tokens - and it was working as well

The following do not work That is they display boxes with unicode values

   WikiPedia - https://www.wikipedia.com
   Facebook - displays boxes with unicode value https://www.facebook.com

The following work with proper english text

   FireFox Privacy - https://www.mozilla.org/en-US/privacy/firefox/
   Trivago - httpd://www.trivago.com?_wr=1&<lots of tracking parameters>
   YouTube - https://www.youtube.com

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Edition Windows 10 Home Version 21H2 Installed on ‎09-‎Jun-‎20 OS build 19044.1466 Experience Windows Feature Experience Pack 120.2212.3920.0

Firefox: 97.0 (64-bit)

I have Thunderbird installed on two computers.

On one of the computers, emails being held in my inbox are being automatically removed after two weeks (this is not a desirable action, I am loosing important emails), but on the other computer that is configured exactly the same, emails remain in the inbox indefinitely (which is desired).

Both computers are POP and both configured to run the same email account and appear to have all of the same configurations and settings. I saw someone had posted the same problem a while ago and the reply indicated it may be that the ISP or email provider has their settings set to delete emails as per the two week window, but as I can assure you this is not the case, it is a configuration issue with one of the Thunderbird installations, otherwise both of my computers would be deleting the emails while that is not the case.

Thanks,

Just paid $150.00 for a remote session from my computer store. Advice is: My older computer (2004)and it's graphic capabilities aren't compatible with newest FF. So I'll stick with older version (9) until I decide to get new computer. Firefox is my preference, but if I update, it's likely to break again. Please tell me how to stop all update notices. It is maddening. Or, if you can do it, please do. I don't want to use the others. It has crashed twice, just FF, in the last few days. A system restore saved me, but I updated and lost it. Can you help this not wealthy person? I thank you for your fine product, and your help.

Hi, I updated my version of Thunderbird by downloading the latest version and installing it as opposed to allowing Thunderbird to automatically update. The basic reason was my old version didn't support OAuth 2.0 which I needed to continue using my gmail account. After the update, I had 2 problems. First, my address book was empty but I have solved that from a backup Profiles folder I have. The second problem is when I start Thunderbird I get the following error message in the pane that would normally show the last email in my inbox:- "File not found

The file mailbox:///C|/Users/blogs/AppData/Roaming/Thunderbird/Profiles/ohv7zad7.default/Mail/Local Folders/Inbox cannot be found. Please check the location and try again."

The 8 digit default file is showing a different 8 digits to my actual Profiles folder. What do I need to do to prevent the error message appearing every time I start up Thunderbird, All my old emails are appearing as they should. Thanks PL

Hey folks, hopefully you can help with this mysterious issue!

I've been running Firefox successfully on my Windows 10 PC for a long while now. Last night, for some reason it simply ceased to work. New windows and tabs would not load any content. I also couldn't access the Settings at all (clicking on Settings in the browser menu produces no results or feedback.)

Yesterday, I had Firefox open all day (I usually have my computer on all day), and it was working fine. Around 8 or 9pm, I first noticed that none of my open tabs were loading any content, and the tabs had the "loading" animation playing. New tabs would also not load any content. I assumed it was an internet issue as I did see my internet connection get disrupted once or twice. I did not see anything (apps, etc) on my PC updating.

This morning I found Firefox was still not loading anything, although my internet connection was fine. I tried opening Chrome, and it ran just fine. Everything else that it is internet or cloud based on my PC is running fine too. So it seems to be an issue just with Firefox.

I have listed my steps to troubleshoot below, but I want to note one weird thing I observed: Even when Firefox is closed, and Task Manager doesn't show any Firefox processes open, my PC seems to think Firefox is running. For ex. while trying to uninstall Firefox or delete certain files, I would get a warning to "close Firefox first" or "can't perform this action while app is running." After seeing these, I would again confirm that Firefox appears closed and Task Manager shows no related tasks.

My PC build: - Windows 10 Home, 64 bit - Version 20H2 at start of issue (updated to 21H2 during troubleshooting) - OS build: 19044.1526

Things I have tried for troubleshooting already: - I have WebRoot on my computer due to my job, and I asked our IT staff if they could see WebRoot blocking anything related to Firefox on their end. They said it was not. - Used "Firefox Refresh" - Uninstalled and reinstalled Firefox - Cleared app cache / app data - Updated Windows from 20H2 to 21H2

Note: This message was sent on a different computer & browser

When I am typing an address or search term in the address bar, something happens to convert fl to "I. For example, as I type netflix.com, it ends up being net"Iix.com. The address still works (I end up on netlfix) but it looks like there is a bug in how the text is rendered in the address bar. I am on Firefox 100.0.2 on openSUSE Tumbleweed

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

• My mail client is completely unaffected and is behaving normally.
• I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
• Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

In Firefox, my instructor and student grade sheet no longer displays the horizontal scroll bar to bring more data extended off to the right of the page into view. I have an image attached where the scroll bar should be present. This begin in May sometime, and I'm not sure how to fix. I have tried re-installing fresh a few times, and removed any custom settings that might have been in place. Any and all help would be VERY appreciated as one of colleagues is super frustrated and I would love to find out an answer for both him and myself.

Login to my Thunderbird account has failed for the second time in less than a month. The first time it happened, the system seems to have fixed itself. This time, it is locked. See the attachment showing the error message. I vaguely remember being advised a few years ago to delete something in my TB and reinstall, that the content of my account is stored elsewhere and would reinstall. Is that correct?

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.
