Firefox supportforum

Greetings everyone,

I've had this problem for a while and I don't know what to do.

I had a problem where Firefox kept crashing before it had finished loading up all of my former tabs and windows and so I was given the option of opening Firefox in "Safe mode" which I did, but now Firefox only starts in "Safe mode"...

I'm running the most up to date version of Firefox.

Thank you for any help!

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

Hi friends. We have had some recent power outages when everything was back up running my youtube screen only shows the video but everything else is white. I will try to attach a screenshot.

I am running an iMac with system Sonoma 14.4.1 installed.

I have used Firefox for over 10 years with no problems.

Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

Hello. I have put my language everywhere on the settings which is latvian. For possible translations i have only put english. Some pages, for example, whatsapp web is showing in russian ( i mean the app data for sure, not the messages), also some homepages i use open automatically in russian. How can i put latvian by default or if its not available for the homepage, put english automatically?

Yesterday I was playing videos on rumble fine. Sat my laptop down, picked it back up after waking up and suddenly no sound on any rumble.com video. Youtube plays video and audio fine. So does X and truth social. In fact, any website plays audio EXCEPT rumble.com. Its not Windows related. Its firefox related. I installed Chrome and rumble.com plays with sound fine. I uninstalled firefox and reinstalled and that didnt fix it. I have rumble installed via WebCatalog an it plays videos and audio fine. I then installed Firefox nightly and never signed in or anything and still rumble isnt playing sound. Its rumble+firefox=no sound. And it appears to be happening to others too on other help forums. DOES ANYONE KNOW HOW TO FIX THIS?

I've spent a long time tidying up the passwords on my main PC. Every so often I did a manual sync too. I also imported into Edge occasionally and I noticed a few sites' details there that I had deleted from FF. Strange! Anyway, I finished the tidy up and went to my Android phone (set up to sync) and did the sync there and it looked OK. I then had the idea to look here for the 'extra' one I had seen in Edge and sure enough it was there! I also noticed lots of others I had deleted from the 'Master'. Changes to passwords had been replicated successfully though. What is the logic for syncing in these instances? I then signed out of FF on the phone to stop the sync and deleted one that was common to both and then signed back in and synced - it did delete it from the PC when I synced that. This makes me nervous to delete them all from the phone when signed out and syncing upon re-connect. So, what is the safe way to make the password details from the PC be an exact copy on the phone - no extras?! My thoughts were to disconnect the phone (but hoped it would remove things), delete the details manually if required, sign back in and re-sync. But I don't want to risk the sync actually wiping out the contents of the PC! Thanks! TL;DR - how can I safely remove the synced contents from one device and then resync it. Currently, the contents across devices is different after a sync.

in my account my questions here ,in this firefox forum , i see my questions about... thunderbird! its strange,right? i look for my questions and asnwers in this forum. so where are they ?

After updating my openSUSE Firefox package from version 122 to 123 every frame inside each window started to have weird grey overlay of scrollable area. I failed to find any description of such a thing happening, let alone how to get rid of it. I tried removing build-in distro-default preferences and had complete audit of all my custom preferences in about:config but none changed that behavior. I even updated to 124b4 but this also haven't changed anything. Naturally, nuking entire profile is not an option, I might as well replace the whole browser. So, how do I get rid of this thing?

Hello,

For an unknown reason, my firefox sometimes is really slow to startup.

It can take up to 10 minutes before the webpage start to load. My hardware is not that bad. I try to use the "performance" to capture the issue : https://share.firefox.dev/3x2rgHj I don't know if there is something to see because, the tool is also slow.

It happens on 3 different computers on linux.

I try to disable all extensions and without telemetry but nothing change. I'm reporting the problem now but it's much older

If you have a idea to fix this issue please share because it's really annoying.

Hello everyone,

I posted my issue on the french speaking forum a few days ago https://forums.mozfr.org/viewtopic.php?t=153652&sid=96223ded5b326b4da4114d4c0fb4b740 I think I've had this bug since the last update of Firefox. I have checked on other browsers (Edge and Opera), and I have no problem with them. Its also ok on my mobile phone ... with Firefox !

Thank you for your attention and any help you can provide.

Regards Damien

The most recent update, has caused my firefox to not work properly. Firstly i noticed that it reset all my extensions and themes and now i have noticed that it has affected some sites i was storing data on, for example, i use a site which keeps a track of all the camos i have achieved for Call of Duty MW3. This has now been reset. These can all be redone, but it is something i shouldn't have to do, with an update, as it has never happened before with a firefox update. The way it has been going, i am sure i will find more errors with firefox. Hopefully something can be done, maybe not in this instance but in future "Improvements", as it is not a good user experience!

My computer messed up today and i had to recover it, but i didnt get to save my bookmarks. I've had a mozilla account since 5/2/2024 (i think, thats at least what it says was the date i made my password) and i've saved a lot of bookmarks i cannot lose.

i forgot what email i had made it with tho, so i created a couple of new mozilla accounts and idk if that has messed up the profiles i'm using? i read the mozilla guide on bookmarks and i have like 3 profiles under "profile:default-release" (my settings are in danish, idk if that's what its called in english). but i cant tell which one it is? furthermore, when i click on "manage bookmarks" i get to this place that says something about bookmarks saved on html or something - which i know i havent done.

oh also, before any of that, the first thing i did was synchronize my google chrome bookmarks with firefox and idk if that has messed something up?

So I have a following problem

After installing Thunderbird i had first download problems for new Firefox Versions. I tested around, installed everything new and found the solution. Somehow the Maintenance Service didn`t work properly on my machine and after deinstalling and restarting i can update firefox again. Problem remains: When trying to install Offline Languages , see picture, i get the message that it does not work. I tried everything possible, including reinstalling and deleting all old profiles (was a lot of work). Any ideas?
