Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.

Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

My browser stopped loading certain pages, like Instagram, Facebook, and Amazon. Caches are cleared, extensions are disabled, tried service mode. Other browsers seem to have no problem loading these sites. What can be the problem?

Dear Support Team,

I am writing to request assistance with an issue I encountered after a recent Firefox update. After opening the browser, an automatic updat led to making all of my bookmarks, saved passwords and website data disappear. The profile I was using had been active for over two years and contained important information that I now cannot access (it wasn't a profile I created myself, I just used the browser normally).

I have already tried several troubleshooting steps, including restoring previous profiles, checking the profile folder, and attempting to recover data from backups. Unfortunately, none of these attempts have been successful so far. The about:profiles website tells me my old profile does not exist but in my Firefox folder, there is a (profile?) folder from 2023 which contains only one file.

Could you please help me recover my previous Firefox profile or guide me through any additional methods that might allow me to restore my lost data?

Thank you very much in advance for your support.

Kind regards, Sophia

Hi! So I just installed firefox and I got onto annoying issue. I like using shortcuts on my homepage, but I started to get some shortcuts added automatically and they bother me a lot. I tried removing them or deleting from history, but as soon as I click the button, one shortcuts gets removed and immediately gets swityched with another one automatically. So I'm stuck in the infinite loop of removing shortcuts and my manually added ones just get lost in all this mess.

Has Microsoft blocked Mozilla from access my hotmail.com Outlook account now that MS has bought out hotmail.com? I have Windows 11 on my PC and I can't reach my hotmail.com acct via Firefox browser, please advise. Thanks.

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?

This is where you describe the issue in detail.

Explain what’s happening (e.g., “Videos keep freezing after 10 seconds”).

Mention when it started and what you already tried.

Include your Firefox version (you can find it under Menu → Help → About Firefox).

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

I have an website which I prior to this error message have visited many times on Firefox and had no problems. Recently though around two days ago I noticed that I couldn't get in and was met with the following message "Warning: Potential Security Risk Ahead". I can't bypass it apparently and I really need to be able to access this site as it's a University site.

I can access the site on other browsers such as Chrome and Edge but I use Firefox as my default browser and I'd like to keep it that way. I'd appreciate any help I can get.

Hi All,

I would like to remove the first item from the Tab Context Menu, which is "Add Tab to New Group", and simply have "Reload Tab" as the first menu item.

I was using this code, which worked in FF 145, until the latest update (FF 147)...

#context_openANewTab,
#context_moveTabToNewGroup,
#context_moveTabToGroup,
#context_ungroupTab + menuseparator {
   display: none !important;
}

However, now there is an extra separator line at the top of the menu (see attached images).

This code also removes the top menu item, but still leaves the separator line on top:

#tabContextMenu #context_moveTabToNewGroup {
  display: none !important;
}

Is there a way to remove the first menu item without adding the separator line?

Thanks!
