Hi. i ran into a broken problem. sometimes when i bootup my pc and start the firefox, My windows crashes immediately. what shuld i do and how i can send the firefox log files to mozilla team?

alright guys you need to fix your browser, it crashes everytime i try to play a youtube video.. i searched tou site for fixes and NOTHING worked. you vanilla version of the browser was perfect then yall had to go and do the microsux thing and screw it all up by adding this that or the kitchen sink. i have submitted numerous reports yet no resolution. if you guys dont fix your crap i will move on to another browser and recommend to all my friends n family to do the same.

Switching to Protected Browser... COULDN'T LOAD XPCOM.!! it stopped a month ago and yet to get an answer , from you guys. It seems no one want to answer or try to find the error issue. Uninstall firefox and reinstall!!! No by doing that you will lose all of your data thats attached to firefox anywhere from you bookmark to user names and so on, Thas not a good solution AT ALL!!

For about a couple of weeks, there has been a lot of delay between what I type and when it actually appears. It's maddening! I have not changed any of my Firefox settings. I did a 'refresh' about an hour ago. I am not seeing any network activity that I cannot recognize. I d/l'd 'Malwarebytes' and ran it..."no threats". MS Defender has always been on & protecting me. I have never had this situation occur before and am hoping for some help (5 to 10 seconds to wait for what you've keyed in is not fun).

Settings > Home > New Windows and Tabs > Homepage and new windows

This setting got reset on me last night. Using 127.0.2.

So, I set it to custom, add in a URL, close the settings, re-open the settings and see it is set.

I close my non-pinned tabs and then close the browser.

Upon opening the browser, I am greeted with an empty tab and the Setting has reverted to "Blank Page".

I am using Linux Mint with Firefox 127.0.2 (64-Bit)

In Preferences Applications, setting

 CSV-Dokument      to    open with firefox

opens edless new firefox Tabs - so I had to kill firefox. (setting CSV-Dokument to open with OpenOffice works fine. But this is not what I want.)

In Preferences Applications, I found further CSV types: application/csv-Typ CSV Document (application/text) CSV Document (octet/stream) CSV Document (application/x-download) Which applications should I use for them ?

I found the file "mimeTypes.rdf". However, I am not familiar with the syntax.

In an earlier version I set it up so that opening a tab opened about:blank and the title was blank via a simple Greasemonkey script:

// ==UserScript== // @name blank // @grant none // @include about:blank // ==/UserScript==

document.title = "\u2800";

Now not only did Firefox restrict what could be set on opening a blank tab, (which required me to install an add-on), the Greasemonkey script doesn't work on about:blank anymore.

NOT to remove personal data? Does it give you an option for personal date not to be removed?? what about all the stored password? Can one of you tell me why all of sudden I get this error COULDN'T LOAD XPCOM? can you send me a link where to reinstall new version on top of the one I have running now Thanks

I lost my account, it was b. I'm doing my best to recover an account under bbm.N CHA ca.net@gmail.com. I had also did a fire an account, but it did not go through.And i'm having complications getting back into my accounts

Hi!

I've been having consistent trouble getting firefox to save my passwords. I'm signed in, have all the password-managing options enabled, and I import my passwords from chrome (which I've wanted to stop using) but my saved passwords tab is always empty. The next time I use firefox and I'm logged out, it's all wiped clean. When I try to synchronize my settings and passwords after importing again, nothing happens when I click Synchronize.

I've restarted the browser many times, opened it in Troubleshoot Mode (here I was able to import, save my passwords and synchronize just fine), went on to disable all my extensions one by one, themes, and hardware acceleration, but when I opened the browser normally, the problem persisted. I don't know what to do at this point!

I'd appreciate some help, thank you.

Problem: When exporting or downloading content from the GUI in the digital forensics tool Velociraptor, underscores are appended to the beginning and end of filenames. File is otherwise downloaded correctly, but removal of underscores necessary if original filename is desired. One hypothesis is that perhaps for security reasons there were changes made in Firefox 127 for how character escaping is performed.

Tested Operating Systems: Ubuntu 24.04, Windows 11 22H2, Windows 11 24H2, macOS Sonoma (14.5) Affected Firefox version(s): Confirmed 127.0, 127.0.1, 127.0.2 Tested Firefox versions which do not reproduce the behavior: 126.x, 125.x > Testing Microsoft Edge, Chromium, Google Chrome on Windows, macOS, Linux: files download with correct name as expected. Testing performed with clean installations on clean VMs with no add-ons enabled.

To reproduce: Download the latest release of Velociraptor from Github (at the time of this writing, 0.72.3) for preferred platform / operating system. Run Velociraptor using the gui switch, e.g. "$sudo velociraptor-v0.72.3-windows-amd64 gui" or "$ velociraptor-v0.72.3-windows-amd64.exe gui" Navigate to Server Artifacts and click the "+" icon at the top Search for Server.Utils.CreateMSI - select and press Launch Select the newly-created flow, click "Uploaded Files" tab and click vfs_path to download the file or, click the Notebook tab and click Download JSON or Download CSV buttons to download JSON or CSV respectively, underscores are appended to beginning and end of filenames.

I know I can set Firefox to offline mode by pressing Alt on my keyboard and choosing "Work Offline" from the file menu. However, the browser doesn't actually seem to show me cached versions of sites after I do this. Instead, every site — even sites I visited literal moments before switching to Offline mode — shows me the same "Firefox is currently in offline mode and can’t browse the Web" message, and invites me to "Try Again" to go online. But I don't want to go online. I want to see the version of the site that, I hope, at least if Firefox behaves as I'd expect it to be have, is already saved in my computer's cache. How can I achieve this?

I use Firefox to access my bank account, and it autofills the personal id number, and, when I click, the 6 digit code, which I allow it to store, because no one else has access to this PC. BUT, I had to take it in for repair, and give them my Windows login details. When I got the computer back, I went to the bank login page, and the autofill was a different personal id number. Does this mean that somebody used Firefox on my machine to login to their account? Or could a reboot have meant that Firefox randomly changed the PID number? Thank-you for your help.

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?
