When I click on a link on Firefox / Mozilla I get a "Hmm. We’re having trouble finding that site. We can’t connect to the server at ad.doubleclick.net" message. If I do the same on Brave, that doesn't happen, it will show the link that was clicked on. What can or may be the problem? This happens way too often, for example on "Newsmax" links.

in the last couple weeks, every time I go into Firefox my bookmarks and bookmark toolbar are scrambled. (all messed up and out of order). I have to keep restoring from a good save file. How do I stop this from happening? I have even uninstalled and reinstalled Firefox, but that hasn't helped. I have imported the good bookmark file that I saved.

I enter msn.ca on an open tab, https://www.msn.com/en-ca is displayed in the tab window but no content is displayed. No extensions are enabled.

Works in Edge browser. Also doesn't work with Brave browser

I will visit a site, say engadget. Then I can open another tab, and I expect when I type en or eng or engadge that it'll autocomplete to engadget, but it won't. For some sites, it works, for others, it doesn't. I'm a developer and am used to figuring stuff out, but no matter what settings I change it doesn't consistently work. I use Firefox on all my devices but on this one machine, it doesn't work. I've triple checked the settings. I am this close to switching browsers, it's so frustrating. Any ideas would be greatly appreciated.

Hi all,

I would like to know if this color issue is expected behavior or a bug somewhere on my system.

I am using a monitor (Acer ET322QK wmiipx) which displays color at a depth of 10 bits per channel (for a total of 30-bit color depth). When viewing images which have color depth exceeding 8 bits per channel, color banding is visible in Firefox that does not appear in GNOME Image Viewer, indicating that the image is not being displayed at the correct color depth. I've attached an image with 16 bits per channel color depth as an example. This sphere render is deliberately dim to make color banding more obvious. It should look smooth/unbanded on a display with support for colors with greater than 8 bits per channel.

By opening the Firefox console with Ctrl+Shift+K and entering "screen.colorDepth", I have confirmed that the display is identified by Firefox as having 24-bit color depth.

Since the last update that I received from you and installed I can not longer get in to my online Bank account. I get a window telling me access is denied. I am unauthorized to access this resource. with a Reference ID of e727ec65b1 Troubleshooting steps 1. Reload the home page and try again Failed 2. Clear your browser cache and try again. Failed 3. Try logging in with a different browser. No they aren't as secure 4. Try logging in with a different device. No only use my desk top for business.

The Bank says they are having trouble with Firefox. I don't want to have to use Edge or Google they aren't as secure as Firefox. Please fix this with the Horizon Bank. Thank you. dleeb17

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

I left my computer for a while, and when I returned and took it off screensaver I started going through my emails when I noticed that the bookmarks on the toolbar are missing. The toolbar is present, and I toggled between only show on new tab, never show and always show a few times, but they're still missing. I even tried bookmarking two webpages, but they were not added to the toolbar. As stated, I have the bookmark toolbar to always show. Firefox just updated yesterday, 4/8/25 to 130.1.0, and I'm pretty sure that they were there this morning, but I can't be totally sure. I noticed my computer had updates available, so knowing updating it would not have any effect on Firefox, I restarted the computer while updating so I could also restart Firefox with a bit of a delay. I had also restarted it twice before without any luck. The only thing I did besides updating Firefox was enabled the sidebar, which I then turned off and still did not have any bookmarks in the toolbar. Any assistance would be greatly appreciated, but I may not be able to view and any responses or make the stated changes until Friday.

I'm getting constant crashes with my browser getting the crash reasons EXCEPTION_ACCESS_VIOLATION_READ EXCEPTION_BREAKPOINT

I use Firefox on a ASUS Vivobook running Windows 11. On April 1, it tried to update to version 137.0, but failed and led me into a update loop of sorts. I had to re-install Firefox just to force an update on it, and that worked for a bit. Just today, it decided to update... and led me into ANOTHER update loop, and it's saying that the "install failed" when I check the update history.

Is anybody else experiencing this bug, and is there a way to fix it?

I have removed Firefox and installed fresh the latest version 137.0.1 to address the issue of not being able to start a new tab or a new window. I am writing this from the initial window that opens when Firefox is launched. If I try to open a new tab it will hang with the blue circle displaying. If I click anywhere on the window if will grey out the background and display the error message :

Firefox is not responding

if you close the program, you might lose information

-> Close the program -> Wait for the program to respond

Tried waiting and it never comes back. Only option is to close the program. After that there is a message that is reporting the issue to Microsoft.

Hello

With the new update to Firefox v137 I am no longer able to sign in to Government sites using my bank as a sign in partner. Google Chrome will sign in so it has something to do with the new update. I have cleared cache and all data and still no luck with the sign in. Any help would be appreciated because Firefox has been my default browser for years and I'm not interested in changing.

Regards

For years I have been able to watch a foreign TV website, despite having only a DSL connection (I allow only the scripts essential to make it work). Since I did the last update, to 137.0, I cannot watch either the live stream ("General source error") or old programs ("There is something wrong with your internet connection"). This is absolutely consistent; I've lost count of the times I've tried.

I never had problems like this before. At worst, if Windows was running a background process I might have to stop it to keep from having pauses in the program. All I can think of is that you did something in the new version of Firefox that has made video impossible on DSL.

The proxy settings just don't apply. I set the settings on the system, all programs work via proxy except Firefox (set to use system proxy settings). If I set the proxy manually in Firefox, the connection still doesn't go through the proxy.

I found that only the very first connection after starting Firefox goes through the proxy, absolutely all subsequent connections do not go through the proxy.

Ok for some reason any of my browsers tabs are crashing I just do whatever it is whether i search or watch movie and after some time 'Gah! your tab crashed' and it's pretty annoying, my discord happens to restart it self and I've exhausted literally anything from re-installing, deleting caches folders absolutely anything.
