Firefox Community Forum

Hello everybody, i hope you are having a great day!. I have a problem with Youtube about the frames drops, in 1080p60fps i have drops but in 1080p normal don't. For system operative i'm using Fedora 43. And the Firefox version is the 145.0.1 64 bits. My specs are low: Intel i5 6200u with his integrated graphics (Intel HD 520) Already installed the extension h264ify, and i think i have all the correct drivers and codecs from the rpmfusion (ffmpeg, mesa freeworld) If u need more detail and information i can give it to you. Thanks for anyone that is interested in help me.

Firefox deleted many folders in my bookmarks file. Then, trying to straighten this out, Firefox has completely changed its home page layout and I can not manage it even in the simplest way. I want to restore everything to how it was two or three days ago.

In the main page (new tab), upper right corner the weather is displayed. However, in my case it shows Paris, France. Been there! - but not in 40years.

the three dots beside the location open a search bar that does nothing. i enter my location... does nothing entered my zipcode... does nothing.

restarted my browser ..... no avail restarted my pc ... no avail

cleared cookies ... then restarted browser ... no avail

Windows 10 firefox ver: Version 143.0.1 (64-bit)

side note: this issue is also on my laptop w11

My instagram does not open on my firefox browser. I have cleard all the cookies and cashes. I tried Incongnito, hot spot sharing. I have tried everything its still not working. Can you help me?

Whenever my laptop starts up,firefox with all of my tabs always starts up with it. When i rose up earlier in the day and started up my laptop firefox with all my tabs opened up as normal,but this evening everything is gone. I had at least 20 tabs open and they were all important. There was no option to recover the tabs and this isn't the first time this has happened,this is at least the third time that this has happened after the last year and a bit. This is incredibly annoying and frustrating. Is there even any point in asking the community how this can be resolved?

SUBJECT: Profile missing after update to 146.0.1 

After the last Firefox update (146.0.1), I can no longer access my profile that included bookmarks, history and passwords.  

After the update was done on 12/19/25, I was given the option to choose between my original profile and a newly created one. The next day when I opened Firefox, there was only one profile shown and my original profile was gone. I have read numerous fixes for this problem but nothing seems to work.

I have done the following to try to locate my missing profile to no avail. 1. I went to the Profile Manager but the only profile listed was the newly created one. 2. I didn't do a refresh so there was no "Old Firefox Data" folder to copy the data from. 3. Used about:Profiles, Again only the newly created profile was listed 4. I used ~Library/Application Support/Firefox/Profiles. Still no luck. 

Could my profile have been moved to another place or could it be hidden? Any help would be greatly appreciated!

I downloaded an extension and can't do anything with it. There is no way for me to open it, all I can do is open up my extensions to see it then change permissions or delete it. It won't appear on my toolbar with other extensions. I've seen others ask this question and the solutions dont apply to me. People are being told to either right click and click pin to toolbar or to click the gear icon next to the extension and then pin to toolbar as well. I have no gear icon next to extensions and right clicking an extension treats it like a link. There is a gear at the top that when I click it I can click "manage extension shortcuts" only for it to then pretend none of my extensions have shortcuts even though 2 of them are right there in my toolbar. The 3rd 1 mozilla seem to not want me to have on my toolbar.

With Firefox 144, there is unasked for/unwanted AI introduced. How do I ensure that all AI is completely disabled in my browser? I found a link describing some settings, but want to confirm this will disable ALL AI in the browser. I don't want it, don't trust the privacy/security holes yet to be found and would prefer it was not included in Firefox to begin with. The list I've found is:

• user_pref("browser.ml.chat.enabled", false);
• user_pref("browser.ml.chat.menu", false);
• user_pref("browser.ml.chat.page", false);
• user_pref("browser.ml.chat.shortcuts", false);
• user_pref("browser.ml.chat.sidebar", false);
• user_pref("browser.ml.enable", false);
• user_pref("browser.ml.linkPreview.enabled", false);
• user_pref("browser.ml.linkPreview.optin", false);
• user_pref("browser.ml.modelHubRootUrl", "");

Will this do it? What about:

browser.ml.chat.nimbus

Do I need to clear that field to ensure I don't get some auto opt-in in the future as more and more of this "stuff" is put into the browser?

Why not leave Firefox as a security/privacy conscious browser and put out a separate AI browser (FirefoxML?) for those that are not as concerned. How does Mozilla ensure that no information is leaked through AI from sessions for professionals that must protect physician/patient, attorney/client information or other legally confidential information?

My problem is that Firefox will no longer allow me to login to my primary websites (email, bank, Costco, Apple...). I originally assumed that my outdated version of the MacOS was the problem, which was tied to the age of my outdated iMac hardware. Hence, I bought a new iMac, with the latest MacOS. Firefox still does not work. There is something wrong with Firefox and I don't know what it is. I have captured screenshots of the symptoms of what goes wrong with each website, but the one thing in common is that they are saying it is an application error on my end of the connection — which must be the browser (Firefox). I am being forced to do my daily business with Safari, but that is a strange browser for me, and they do not have my numerous Bookmarks. Also, their way of storing bookmarks is very strange, so I only have 5 — the ones that I have found so far that do not work with Firefox. There are probably more, maybe All of my bookmarks, but these are the 5 that I need every day.

Figure 1. Outlook (my email) When I log into my email, the result is Figure 1. This appears to me an application error on my side of the connection -- i.e., Firefox.

Figure 2. Costco.com When I log into Costco.com, the result is Figure 2. This appears to me an application error on my side of the connection -- i.e., Firefox.

Figure 3. Apple.com When I log into Apple.com, the result is Figure 3. This is Apple telling me there is something wrong on my side of the connection -- i.e., Firefox.

Figure 4. BankofAmerica.com When I log into my account at Bank of America, everything looks fine at first. But when I try to open my checking account, the result is Figure 4. This symbol, swirling forever, indicates something wrong on my side of the connection -- i.e., Firefox.

Figure 5. Hallmark.com When I log into Hallmark.com, everything looks fine at first. But none of the links will open, hence I cannot obtain any information about upcoming TV programs. This indicates something wrong on my side of the connection -- i.e., Firefox.

All the above examples work perfectly with Safari. Firefox is supposed to be the most up-to-date browser, so why has Firefox stopped working properly?
