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.

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?

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.

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 have set Firefox to not automatically restore the previous session on launch. That is, "Open previous windows and tabs" is unchecked in the Startupsettings.

Most of the time it does not do so, however the previous session will get erroneously auto-restored in the folowing circumstances.

Open a few tabs in a normal Firefox window. Fully quit Firefox (via, for example, pressing ctrl+shift+Q). Open a private window first. Open a normal window second.

What should happen is that the new normal window contains just a single new tab. What actually happens is that the tabs that were open in the previous session get auto-restored in this normal window.

To sum up, there is no auto-session restore if Firefox is launched with a normal window first. There is auto-session restore if Firefox is launched with a private window first, and then a normal window is opened second.

Is this a known issue, and are there any known fixes to prevent the auto-session restore in the latter case also?

I'd love to find a solution! Sometimes this happens when opening a link from my email (to a well-known retailer as shown in the images below), and at other times it is in response to a website requesting information as part of a 2-factor ID request or, or even a password change. It has become almost almost debilitating! What setting seems to be wrong here.

I use Webroot SecureAnywhere and the relevant updates are applied automatically.

How do i access Google OneDrive via Firefox so as to delete my sensitive personal info such as financial PDFs and personal pics, which involuntarily got copied to Google OneDrive thru an erroneous mouseClick?

See, when i keyword search online, it states that Google Drive can be accessed via one's browser for purposes of accessing/deleting one's files. (Frankly, i don't even know if OneDrive is GoogleDrive? Is it?

It's upsetting to me that Google has loads of my personal info, because over the years everyone has been saying "Use Gmail", and so i made that my main email due to convenience. But Google now has, for example, some of my personal home photo's and private financial PDFs, all because I absentmindedly clicked my mouse on a risky part of my email attachments, not realizing that would transfer the JPG (or PDF) to Google OneDrive.

I believe this started happening ever since they imposed the New Gmail without giving us a choice. Prior to that, when i used HTMLgmail, i don't recall this happening when i clicked attachments. With Simple HTML, if i clicked an attachment, i saw a photo. It didn't INVOLUNTARILY auto-transfer my pics/pdfs to Google OneDrive, which precisely reminds me of automatic faucets and towel-dispensers and light-shutters in public buildings, all of which are human-unfriendly.

Mission Federal Credit Union account page loads but does not allow account info to load. Mission Federal tech say it is a problem with Firefox. Please fix. same problem through two updates of your software.

My (custom) cursor has recently started being transparent when I hover over a YouTube video. On darker colors it's fine, but on white it's straight up invisible. I tried recording it, but the recording doesn't capture the transparency. This didn't happen before, I changed nothing.

I have lost recent activity on home screen. There are blank tiles but nothing is being added.Hovering over tiles nothing happens. How do I get recent activity to appear again ?

For several months, Firefox has been unable to play videos from various different websites, including Netflix, Paramount Plus, Youtube, and others. I've turn off VPNS, reset my internet router countless times, cleared cache/cookies, flushed DNS, updated firefox, updated my video drivers, updated windows, disabled extensions (including adblock), opened Firefox in safemode, and reset hardware acceleration. This is not an issue on chrome or edge. Some of the error messages include: Netflix F7351, Paramount Plus 5000, and error code 102630. Youtube mostly doesn't work on livestreams, and says that my browser isn't compatible.

Dear supporter, our firefox is managed by our company, while download file, not sure why some file type could not setup default option, due to no check box "Do this automatically for files like this from now on", could you share how to fix ? Thanks a lot.
