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

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.

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.

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.

Regards, Renee Invivo

When I switch from one tab to another doesn't matter the webpage the page adjusts the content on the tab. For example I was on youtube and switched over to gmail and it adjusted the screen and when I switched back to youtube it did the same on youtube. I wasn't zoomed in or anything. I was just on the tab and it was fine and looked how it should but as soon as I switch to another tab it does it on that tab and then will do it again when I switch back to the tab I was on originally on. I'm on FF vers 113.0.2 (64-bit).

There are many mainstream websites that have stopped functioning in firefox that work perfectly fine when switching over to brave and enabling scripts

these are not obscure sites, they are sites for privacy protecting entities hence the lack of function on firefox is perplexing

how do we make these sites work in firefox again to save the switching to brave?

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.

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?

Why again? After I reboot my pc and re-install firefox, I re-install back the Google Translate (GT) extension, it's not working like las time anymore.

It used to be I just press translate the entire website will auto translate..now after i reboot my pc and re-download latest Firefox, ur GT extension turned into shit. I add-on this extension 'To Google Translate by Juan Escobar' ...i use on the Chrome, no problem, I can translate the entire website. but I added back the same extension 'To Google Translate by Juan Escobar' in your Firefox it's different! WHY IS THAT? Pls view attachment. It used to be the same with firefox...what happened after the re-download to the latest version Firefox after rebooting my pc?

OS VERSION: WINDOWS 10, 64-bit CURRENT FIREFOX VERSION : 70.0.1 (64-bit)

Thanks,

I find out how to hide images while loading the website on Firefox 102.0 but what I also want is to hide the SVG icons on the website. How can I do it? Thanks in advance

The old PC is dead, there is no back-up/export of the saved passwords and no sync. I can only access the disk content when connected to another PC. Where and in which files are the Firefox saved passwords stored in and can I see them or import them in the new installation?

The last update 113.0.1 was when I really noticed it being slow. None of the current suggestions have any effect. I have restarted several times, cleared cookies and history, flushed dns and have gone through all settings. Privacy is set at "standard" and not using a VPN and have turned off add blockers with no effect either. I have to check, but I don't think I have any add-ons except for color on home page.

If I do a speed test, ping is kinda slow, download is half what it should be at times, and every test shows ZERO upload all using several sites to test from . The only thing not done is shutting down av which I won't do. Anyone else seeing this issue? Any other suggestions than the go-to stuff here? Windows 10

When opening Firefox for the first time after turning system on for the day, Firefox has for some reason opening a separate window With this address: https://addons.mozilla.org/en-US/firefox/addon/avg-online-security/?src=external-app-newtab-store I do use AVG as my anti-viral program but am not interested in using this add-on. I have looked in Firefox setting, and can see no way to stop it. Do you have any ideas, PLEASE? I will try to add a screenshot of the screen for you to view, if that helps!! THANK you!!
