Hi, my Machine updated from 140.0.4 to 141.0 since then I cannot start up Firefox anymore. On startup after a short pause the Crash Reporter shows up - interestingly the Crash Reporter may enter a endless loop and opens up multiple times. While that the CPU load is at 100%. I tried

  • `firefox --safe-mode`
  • `firefox --ProfileManager`

as well, for those I get the same behavior. I tried downgrading to 140.0.4 - after that a profile dialog shows up which tells me that a new profile needs to be created due to a downgrade. After that Firefox comes up fine with the new vanilla profile. IF Firefox updates to 141.0 (in background) the next startup with the vanilla profile doesn't work gain. Which brings me back to the initial problem.

Workaround for now:

  • download 140.0.4
  • create a fresh profile
  • immediately disable auto update
  • live with the empty profile

My environment:

As the title says. Youtube pages consume me a lot of CPU (about 15% of usage when normally is less than 1%) and, when opened it keeps using more and more memoy (on task manager i arrived to 44.000MB for a total of 100% on memory) I already tried to refresh it instead of unistalling and the issue wasn't solved. I'm not sure but it seems that there is no memory leak in Troubleshoot mode.

I'm trying to use Firefox to fill out my tax forms, but while I can save them and view them with Firefox, they're blank when I open them with Adobe or print them. This is, to say the least, NOT USEFUL. What is happening?!?? I'm using Win10 and the latest version of Firefox, and I tried it on an old Mac with the latest version of Firefox as well.

Greetings Ya'll,

Firefox Bookmarks are no longer being initially placed in "Other Bookmarks, they are now being placed in the "Bookmarks" that is under the "Open Application Menu" Tab.

I've found that the "New Bookmarks" can be "Dragged" as a copy to "Bookmarks", from the "Bookmarks" located in the menu, for they will stay there unless I delete them

I can not move the "Bookmarks" back to "Other Bookmarks"

Would I lose My Bookmarks, If I "Refresh" Firefox, as suggested in the "Troubleshooting Section? If there is a chance of this happening then that would Absolutely Be Catastrophic!!

"Give Firefox a tune up

The Refresh Firefox feature can fix many issues by restoring Firefox to its default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process."

White/Blank Desktop Icons for Weblinks after Version 141.0 Update 07 24 2025

I have several Web Link Shortcuts (i.e., .url) on my desktop that I created over the years by dragging the web link address to my desktop. The icon for each of these shows the website picture icon. My default browser was FireFox. This morning when I turned on my computer all of these icons were changed to white/blank icons. The icons for programs were not changed just the ones linked to a website. I ran sfc /scannow and no errors were found. I deleted the IconCache.db file and restarted Windows Explorer and my computer, but the white icons remain the same. I changed by default browser from FireFox to Chrome and to Edge, restarting my computer each time, but the problem still exists. The only update to my computer today was the automatic update to FireFox to version 141.0 64 bit at about the time I turned my computer on. I did a search for the issue on FireFox and the web, but I didn't see any recent issues or solutions. I thought about uninstalling FireFox and then reinstalling it, but I saw that if I do that all of the desktop shortcuts become inoperable (I have about 30 of them on my desktop). I have Windows 10 Home version and it is up-to-date. Any assistance or suggestions would be appreciated. Thanks

So, I was downloading some Patreon stuff and Patreon isnt well optimized for browsing older posts. When you have to load multiple more pages dating backwards it slows down the Firefox quite a lot, pretty much to the point when the Firefox reach non-responding state in worst cases.

But luckily for me Patreon worked fine for me tonight, just when I was closing the Firefox, it took like 5 seconds for it to close.

I spent some short time by responding messages on Steam and Discord and then I started new Firefox window, this time I went on Netflix and when the page loaded my monitor went black and then after like few seconds it returned back with "Displayport" message on the top left corner.

When I checked Event viewer, there is nothing at all. When I checked about:crashes, there is also nothing.

Any idea what was that and how to prevent that?

As soon as I select the folder to which I want to save tabs in Bookmarks, the "Save" button disappears. I'm using version 141.0, which it says is up to date. I tabbed through to make the invisible "Save" button active, and then hit Return, and that succeeded in completing the save. But it's weird that I had to do it that way. Any ideas about what is going on here?

(I picked "Performance and connectivity" as the topic only because the form wouldn't submit without picking a topic and it didn't have an "Other" option.)
