I'm running 145.0.2 on Mint Linux and Windows 11...

Like many other users, I have an issue in which roughly half of the icons representing bookmarks on my Bookmarks Toolbar have been replaced by the black+and+white icon of a globe. The links work, but because most of them are now the same, it means I have to hover over them to make sure I click on the link I want.

I've tried: Exporting all my bookmarks to HTML; deleting all bookmarks; re-importing Deleting the "favicons.sqlite" database and letting Firefox recreate it Creating a new Profile and importing all my bookmarks "fresh" in to there

Not only does none of this seem to work, the results are actually inconsistent.

This problem has been kicking around for years - certainly for many major releases of the browser. I understand that there could be deep/complicated issues such as a corrupt user profile, for example...

Unfortunately, however, there does not appear to be any consistent or reliable effective advice on how to fix this issue... and nothing I try seems to resolve the problem.

I'd be very grateful for any recommendations on a reliable repair for this issue.

But I'd also be grateful for suggestions as to how we might go about suggesting to the devs that this long-running bug is overdue a permanent fix.

Thanks in hope.

Hello,

I just set up a computer with Debian 13 'Trixie', and I downloaded and installed the latest Firefox for Linux (version 145) from Mozilla's site.

Then I noticed at first that it wasn't following my GTK theme. Then after testing a bit, I discovered it would respect only themes with names that end in "-dark". I've taken some screenshots and attached them to demonstrate the problem.

firefox-esr from Debian's repositories didn't have this problem. But also, I've got another computer that still has an older distro (Debian 11) installed, and I'm running the latest firefox 145 on that too, and it always respects my GTK theme regardless of whether its name ends in "-dark". So, perhaps this is a GTK/GTK4 problem or something?

Does anyone know about this issue, can anyone help? I would really like Firefox to respect my choice of theme regardless of whether the theme's name ends with "-dark" or not.

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

What settings do I need to get Street View to return the street view rather than a black screen in all 4 of my Ubuntu browsers, when it used to work fine but now is trash ?

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

When I opened Firefox[^1] today I was greeted with a "Donate to Mozilla Foundation" page open, with the message:

"You power Firefox. Now donate to make good tech the default.

Mozilla Foundation — the non-profit behind Firefox — is building a future where technology serves people, not power.

Your donation to Mozilla Foundation keeps the internet open, private, and built for people. Donate today to make good on the promise of the internet."

Does this message mean that Donations to the Mozilla Foundation now fund Firefox development? As I understand it, previously donations were not allowed to be used by the Mozilla Corporation, which actually develops Firefox. I'd love to donate to fund Firefox development, as I feel it is a critically important open source project.

[^1]: 145.0.2 from the Mozilla Debian repository.

I recently tried to connect to two different meeting sites. Both times I got a pop-up noting (correctly) that camera and microphone are blocked. I'm able to click to enable the microphone but I never get the option to enable the camera.

I tried going to Settings>Security&Privacy>Camera but that only allows me to remove previously-enabled websites.

Clicking on the settings button in the address bar shows audio and recording settings but no camera.

What am I doing wrong?

Is it possible to make a donation to Mozilla without providing so much personal information? I got a message on Firefox today asking for a donation, but when I tried to do that, I was asked for my home address. It's a general rule of internet marketing that people who use the internet would rather do anything than pay for something, so it's bad psychology to impose unnecessary conditions when you're asking for a donation. I don't have to provide my home address when I make donations to other organisations, so why does Mozilla need my home address? I apologize if this is the wrong place to ask this question, but I can't find anywhere else to ask it!

Thanks,

Shaun.

Hi,

On some websites (e.g. archlinux.org) most numbers are not rendered. See attached screenshots showing the same page on Firefox and on Konqueror.

In my font settings, I do allow pages to change fonts. Some pages (e.g. this one) do change the fonts and appear well. However, if I disable the feature, then they also break.

I'm using: firefox 145.0.2 (64-bit) archlinux plasma-desktop 6.5.3 wayland 1.24.0

Any idea?

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan

I wanted to set keywords for search engines (in order to quickly change them for a single query). This cannot be done for search engines by default (why?), so I had to delete them and create a new one with the same link and my own keywords. But now I can't give them the same name back, firefox says that such a search engine already exists. In general, it doesn't matter to me which letter is there. The main purpose of my appeal is to draw attention to the fact that search engines cannot be edited by default, because it is quite inconvenient. Thanks for the answer (I apologize in advance if I made a grammatical mistake somewhere, I used a translator) My OS: Ubuntu 24.04 LTS; firefox version: 145.0.2 (64-bit)

I am using Pop OS. Videos are not playing in firefox. In youtube it shows loading infinitly. In reddit all videos become green. I tried playing a downloaded video it also become green. These are only happening in integrated mode. If I use hybrid graphics mode all works good. I attached the about:support page and about:config page.

These files are taken in integrated graphics mode.

I'm building a website from scratch and its going great. I just tried to implement a CSP and it worked except for one small section of my website that allows a user to upload an image and that image is supposed to be displayed back to the user. Anyways long story short the CSP blocked me so I tried to whitelist data: and it still didn't work. defeated I removed the CSP from Nginx to work on it later but when I went to try and test again I get this error. ``` Content-Security-Policy: The page’s settings blocked the loading of a resource (img-src) at data:image/webp;base64,UklGRqbeAABXRUJQV… because it violates the following directive: “default-src 'self'” ``` I have confirmed with Curl and by inspecting the network tab that there is no CSP included in the headers anymore. I have restarted Firefox, created a new Firefox profile, and cleared my cache to the end of time and yet still the error persists. I don't know where or how Firefox is storing website headers but they persists and also apparently work between profiles an implication I'm not going to delve into here. If someone could point me to the file where the headers are stored so I can delete it that would be wonderful.

The AI tab thing is a problem for me for multiple reasons. I found various articles about how to turn it off. They pointed to the following setting: In about:config set the setting "browser.tabs.groups.smart.enabled" to false, and then restart Firefox.

However, when I do that, and then immediately go back to about:Config to check the setting, it has changed itself back to "true".

Other settings accept and keep permanent changes. This means that I'm not forgetting to save the change or anything. Just this one setting (which turns off something causing me problems) refuses to actually stay set.

I see the answer to this question https://support.mozilla.org/en-US/questions/1509077 and tried looking there. There is a completed study called "Smart Tab Groups Rollout", but since it is in the "Completed Studies" group, I cannot remove it.

FF bug (?) (my own tests), Chrome works as expected, was also gemini ai discussed.:

 Why for the following css rule (new FF):
 header:has(~ noscript) ~ * div[class*="-slider"] {width: calc(var(--number-of-slides) * 100%);}
 the --number-of-slides is defined and visible:
 header:has(~ noscript) ~ * div[class*="-slider"] {--number-of-slides: 1}
 but this one isn't at all:
 header:has(~ noscript:has([value="1"])) ~ * div[class*="-slider"] {--number-of-slides: 1}
 And all remembering that in the noscript there is direct descendant having value="1"

As mentioned it works as expected (so average person naturally may think it sould) well for Chrome - noscript is visible, js disabled, controls are visible. Sophisticated use case of :has() but it sort of "has right" to happen.
