I've set up a second profile to keep my personal and work browsing separate. When I reopen my non-default profile, it doesn't restore the previous session's tabs. I have "open previous windows and tabs" checked under Settings > General > startup in both profiles. Please advise.

Hi,

Firefox Developer Edition 126.0b7 (64-bit) shows a perpetual "Loading" screen when trying to access my internal Logitec Media Server at 127.0.0.1:9001.

Other browsers like Waterfox Classic have no trouble, so LMS is working fine.

I tried cleaning the cookies, disabling the firewall (Windows 10), that did not help/

Any idea how to solve this?

Thanks.

The story is when I accidentally clicked on a sick video, YouTube start to recommend me similar sick videos.

So my question is how does YouTube get my identity?

I'm not logged in. my profile is actually a snapshot, so when I restart Firefox, it go back to the snapshot. I even restarted my ISP router to get a new IP address. This did not work.

Only when I create a new profile with "firefox -P" does YouTube start to see me as a new person.

So how does YouTube identify my Firefox profile? I don't think it's in the https request headers. Weird.

I made a small CSS customization to my tabs in FF 115 ESR on Windows 7, so they would be flat on the bottom and rounded on the top, looking a bit more like tabs instead of buttons.

Looked ok in FF 115 ESR.

However, in FF 125, half the tabs are now cut off, including their text (see attached images).

Also the tabs background is darker in FF 115 ESR, providing more contrast between the tabs and the tab bar. In FF 125, it's almost all white and I can hardly distinguish between the tabs and the tab bar.

Why is there such a big difference in appearance between FF 115 ESR on Windows 7, and FF 125 on Windows 10?

Here is the code I used...

/* ------------------ RESIZE TAB BAR ----------------------------- */ \#TabsToolbar { height: 27px !important; margin-top: -1px !important; margin-bottom: 0px !important; } \#tabbrowser-tabs { height:25px!important; min-height:25px!important; }

.tab-background-start[selected=true]::after, .tab-background-start[selected=true]::before, .tab-background-start, .tab-background-end, .tab-background-end[selected=true]::after, .tab-background-end[selected=true]::before {

 min-height:25px!important;

} /* ------------------ RESIZE TAB BAR END ----------------------------- */

/* ------------------ TAB HEIGHT ----------------------------- */

.tabbrowser-tab {
 max-height: 25px !important;
 border-color: #8f939e;

}

.tabbrowser-tabs {

 max-height: 25px !important;
 border-color: #8f939e;

} /* ------------------ TAB HEIGHT END ----------------------------- */

I inserted backslashes at the beginning of the first 2 lines of code above to preserve the hashtag sign (otherwise it displays an index number before those lines), please ignore the backslashes.

I would like my customizations in Firefox 125 to look like the ones I made in 115 ESR.

Is it possible?

Thanks!

Hi,

There many extensions such as:

https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

Thanks.

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

So how do I recover access? Chrome works just fine ... so it is def. a Firefox problem.

I've just updated to Firefox 125 and now, when I start to type in the URL bar and get my suggestion dropdown of previously visited pages, I no longer can see the actual url for each entry. All I see is the top level name for each entry.

This is not helpful, as I may have perviously visited a number of pages on that site and the information shown does not give me a way to differentiate sufficiently between those pages.

How can I get the exact url displayed on the suggestions dropdown.

How can I get those top level descriptions NOT displayed, so that only the urls are shown?

Hi,

I'm using FF on Fedora 39.

However Firefox does not remember any file associations. The MimeTypes.rdf file in the profile is missing and is also not created on restarting the browser.

In the options I've now set the configuration to "Ask whether to open or save files". Now I see a popup when clicking on a file however there is no checkbox with "remember this file associations" (or something similiar).

Hello,

First time posting here, so I'm hoping that someone can help me out.

I'm encountering a very odd issue on my Macbook Pro running MacOS Sonoma 14.4. I am unable to access two sites – allrecipes.com, and seriouseats.com on my home WiFi network on the Macbook.

These sites work on other browsers (tested on Safari and Chrome), and they also work on my iPhone.

Oddly, when I went to work and tried to access these sites via WiFi using Firefox, I was able to.

I am unsure what the problem is – the ability to access these sites on Safari, Chrome, and my iPhone at home suggests that it's not a network issue. I haven't encountered this issue with any other sites.

I am attaching three screenshots 1) The error message that I'm seeing for allrecipes when I attempt to access the site 2) The security tab which shows that the connection is unencrypted for allrecipes (home network) 3) The security tab showing that the connection is encrypted for alrecipes (work network)

Thanks

Video on Facebook plays without sound. The video plays, I see the image normally, but no sound. Video on Youtube works perfectly.

Fresh install without addons or plugins. Switching to "Troubleshoot mode" does not change anything. Youtube with sound, Facebook without sound.

Any ideas where to look?

Hello For a few days now, every time I go to youtube the page appears almost completely blank (see screenshot). I've tried disabling all my extensions and go in troubleshoot mode but it still does not work. When I try removing youtube storage from firefox settings "manage cookies and site data" and saving, data of the same size is still there when I open the storage manager again. The only thing that seems to work is going into a private window but since I have to keep signing in each time it is painful especially with google MFA. Please help.

Thank you

It doesn't matter if I add www.youtube.com site to hosts file in Linux and delete cache, Firefox just doesn't block it, bypassing my meassures to prevent me to get hooked up here. It was blocking everything as expected some weeks ago. I also tried redirecting to different IP's and it didn't work.

After some checks, I noticed:

  • It happens only with www.youtube.com, it doesn't happen with youtube.com (without www)
  • Other common pages like other Google pages, Facebook, TikTok or Instagram, get succesfuly blocked by hosts file as expected
  • I have tested creating new profiles with about:profiles, but the issue continues
  • The issue started after Firefox Developer Edition version 125.0b1 as you may notice in the images attached.
  • I also tested with the latest nigthly version and the issue continues.
  • DNS over HTTP (DOH) doesn't seems to be the problem since it seems that my network doesn't met the requirements to enable it, and if I manually make sure it's disabled, the issue still continues.
  • Chromium browser blocks www.youtube.com as expected, so that indicates my PC might be correctly configured

When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%
