When it happens: - Irregular frequence. The same websites once work once don't. They work with Chrom/Edge/From my mobile(same wifi/router). - Sometimes I have to refresh the page a few times - Happens for all sort of webistes. From local news, to GitHub/Youtube/Google/Any website

Steps I have taken: - Cleared cache/cookies - Reset PC/Firefox - Cleared all extensions - Deleted Firefox (And manually deleted all folders in AppData related to Firefox) and reinstalled afterwards

Nothing helped. Any idea what is going on? I checked Mozilla documentation for SSL issues, but it didn't help either

In my MS Windows 11 system in control panel, Apps > Default apps. Firefox is listed twice. In both of these there are these two separate listings: ".htm" and ".html". Below both these listing it says: "Firefox" "Firefox HTML Document"

Question: Can I remove/delete/uninstall one of these Firefox's? Question: Should I remove/delete the ".htm" and just leave the ".html"?

Hope this makes sense. Thank you for your help.

My old iMac's Firefox browser was automatically changed to ESR (by Firefox) since the computer could no longer update the operating system through Apple (obsolete). When I purchased a new iMac and migrated my data to the new computer, Firefox ESR is still the browser, and says it is up to date. I am assuming I should get the most current regular Firefox version, but don't know if there is an easy way to change the version and preserve all my saved passwords, logins, bookmarks, etc. Looking for guidance. Thanks

Hi all,

I have prompt in Firefox that says "Your browser is being managed by your organisation". I've done a bit of a google and appears to be anti-virus related which I don't have any installed.

Certificates ImportEnterpriseRoots is also set to true.

What would be causing this?

A month ago I started to have problem with twitch. After 5minutes or 2 hours- random times or random tabs, if I have opened more than 1, which is always the case. Some tabs or all, again it's random will give twitch 2000 error and refresh, closing tab,etc nothing will work, except closing WHOLE browser, not just tabs and this is not guaranteed that it will work.

I'm losing my mind with closing whole browser-windows-tabs on different monitors and then re-opening all of that again when I get 2000 error and I always do get it.

Did like 50 re-installs, it's always the same. I tried to go back to older version, but Firefox always want to create new profile saying I have old version installed and I DO NOT want that, I want everything as it is right customized,etc right now.

I'm trying to download Firefox on a new computer. It downloaded the install program at least 6 times in about an hour, but it never finishes downloading. How can I avoid this and get it to actually download Firefox?

Win7 x64P , FF110.0 (64-bit) I am trying to change the image for a 'new tab' shortcut so I can recognize it visually , the only option I see is to select a URL for the image. (local image would be handy)

I uploaded image to drive.google & shared, inserted the link & save. But is shows just blank.
It shared it properly & tested when logout.

but its a share link & not really an image link.

FIrefox v113 on MacOS converts every keystroke entry in Wordle into a FIND command to search the web page for that character. The Wordle site is: https://www.nytimes.com/games/wordle/index.html. Safari handles Wordle perfectly. This problem seems to have begun with Firefox v113. Please give it a try and tell me what to modify. Problems occurs even when I restart Firefox with all add-on extensions disabled.

Hi all,

I'm running 113.0.2 (64-Bit) on Ubuntu Focal.

I just wanted to log into my bahn.de account, got prompted with a hcaptcha which I correctly answered and then got an "503 Service Unavailable" error. The problem is reproducible each time I try. It was working fine when I last tried about 2 weeks ago. I tried disabling addons and tracking protection, deleted cache + cookies + login data as well as cookie files, reset Firefox - no change. Fun fact: The login is working without issues and interestingly even without captcha showing up in Opera and Epiphany (Gnome web browser).

Any suggestions for debugging would be very much welcome. Any hint on why the hcaptcha shows up in Firefox and not in Opera and Epiphany is much appreciated, too.

Thanks, r.

My Navy Federal Credit Union website no longer opens, just a blank white page. I use it nearly daily so now must rely on my phone app. I prefer to do my banking on my MacBook Pro. Here is the link that no longer lets me sign in: https://digitalapps.navyfederal.org/signin/

The link works on my Safari browser but the site isn't fully functional on that browser. I have used Firefox exclusively for years and with this bank. The Browser support info at NFCU says Firefox still works. How do I solve this ?

Thanks

What's the best easiest way to translate my website https://invivobio.net/ in different language. We have different countries visitors so I want to check/translate my English content in different languages after publishing them, so it will be understandable for me and visitors to check the language, is that correct?

Can anyone suggest me Mozilla Firefox Extension which translate perfect because I leave Google Chrome due to slow browsing. I am enjoying Mozilla for the long time, so I don't want to move back to Chrome.

Your suggestions will be highly appreciated.

5eagle: Is there any possibility that the question 'How do I turn OFF FireFox as Default Browser' could be answered? This thread was archived, without conclusion, it seems cor-el Top 10 Contributor Moderator was/is unwilling/unable to provide a solution/answer [2021 ish]. Like 'Shucks ' I would like to 'Turn OFF FireFox as Default Browser' I did not enable via settings so must have missed the opportunity to deselect when installed. If not possible to turn off please advise and I will uninstall and use another. 05 June 2023.

Just recently been experiencing the 400 Bad Request error on Kick.com (a live streaming platform) for about a couple hours now. Never had any issues prior.

Was informed that this same issue is happening on other browsers and the only solution is a "quick fix" (clear site cookies) which only works for literally a second. When the page is reloaded the error message pops back up.

Please help, thank you!

I'm running Firefox 113.02 on Windows 10 22H2 OS Build 19045.2965 on an older HP Laptop.

In trying to resolve an issue with another app, their help desk suggested that I needed to start Firefox fresh with a new profile, that the profile I was using might be causing the problem. My first step was to save and rename the profile that I was using before proceeding, then I proceeded as instructed. I don't know how to revert to the old, saved profile. Articles that I've read discussed too many variables confusing me ; so I'm here to ask help from the community.

The reason that I want to revert is because I lost add-ons that made my browsing life better. I failed to make a note of those add-ons, some of which I've been using for so long that I've lost awareness of them. Bookmarks have also been scrambled and lost. If it matters, I've run Firefox today using the new profile that is missing things I want and need. If browsing today added anything to the profile I will happily do without it to get my old profile settings and pointers back.

I can see the profile that I renamed and saved when I enter about:profiles. I also see several other profiles. I infer that the last profile in the list is the current and default profile, but I'm not certain; so maybe that question should be my second. My first question is can I revert to the old profile? When I see the old, renamed and saved profile, it does not appear with a button to make it the default.

From what I've read, my understanding is that I have to make the saved profile the active and/or default profile so that it will be used by Firefox each time Firefox is reloaded. Do I also have to rename it?

Help will be greatly appreciated and gratefully received.

Dear all,

Any idea please ?

I am on a unstable internet connection and while trying to download a large file it gets often interrupted. By default Firefox deletes the .part file and I am forced to again download from zero. Is there a config that I could change so Firefox keeps .part files so I could continue resuming the interrupted download?
