I encounter PR_CONNECT_RESET_ERROR when accessing to some websites

mainly github google and stackoverflow

Sometimes "Reload current page" will work, with multiple tries

I am in China and I am using v2ray+v2rayA for accessing foreign websites (it is a necessity)

This issue happen only on firefox, as edge and chrome can access without error

Is there some settings to disable the PR_CONNECT_RESET_ERROR feature?

The latest update 141.0 (64-bit) has changed my default save location from g.drive to users//downloads. How do I change it back to g.drive? I use Firefox synced between 2 computers (1 desktop and 1 laptop). I use google drive so that I can access the same information on both devices. I NEED screenshots to be saved in a specific folder in g.drive. How do I do this. Before this update, there was not this issue. Thanks in advance.

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 made the mistake to following Mozilla's advice on why my tabs stopped coming back after I closed out, despite the fact that I had that selected in my settings. Now I'm stuck with an "Old Firefox Data" folder on my desktop and I can't remove it because I need administrator privileges -- but it's my personal PC. WTF

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."

I installed the msix package from Microsoft Store. We can't add our autoconfig to the msix version? We don't have access to C:\Program Files\WindowsApps\Mozilla.Firefox_xxx.x.x.x_x64__n80bbvh6b1yt2\VFS\ProgramFiles\Firefox Package Root so we can't put the needed files there. So were are we supposed to put the autoconfig files? Firefox seems to have added support for the similar situation on linux with flatpak and snap. https://bugzilla.mozilla.org/show_bug.cgi?id=1785278 There isn't a way to use autoconfig on Windows if we choose to install Firefox from the store of the OS?

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?

this is the third time i have asked this. I love firefox but your latest updates have slowed down firefox and does things on its own like it has Ai. Google changes like this too and I will no longer us google. if nothing else let me download an older firefox. Rich Stonehouse

I am on revision 141.0 (64-bit). I believe it automatically updated on 7/20/25 or 7/21/25) PDT. All of my history is gone! There are some bookmarks missing too but those aren't important compared to losing my history.

I only have one profile.

Can someone help?

Thanks.

I use Proton Pass to manage my passwords. This option has mysteriously vanished from available options. Should I simply stop using Firefox? It's not working very well since I have to fight to enter an updated password. I'm MORE THAN disappointed to learn no one is available too help!!!
