Firefox Support Forum

No issues in troubleshooting mode, when I disable all of my add-ons and themes the issue persists. I have reset my browser entirely as well as uninstalled and reinstalled with the same issues.

My old 'Legion' laptop had my (I'd guess) open tabs history from late June! I now have a new laptop, and I logged into Firefox, and didn't see all history from June. I need those 'previous' sessions... Where are They??

I am not computer savy and I have tried every way I know to get to the following web site. Please help me. I put it in and it just says not logged in. I have tried changing passwords and that does not matter. I feel something is blocking it and I am not smart enough and to old to figure it out. https://mychart.clevelandclinic.org/Authentication/Login? Thank you Jean Brummett Jeandet11@aol.com

Hello every professional engineer

I knew how to convert the Firefox file sessionstore.jsonlz4 to .json file by using this website https://www.jeffersonscher.com/ffu/scrounger.html

and after editing the resulting .json file

How can I convert it back to .jsonlz4 file to return it to my Firefox profile as it was?

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?

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?

Hi, I recently opened an account on my iMac with a news media provider. I opted for the Mozilla-generated email mask and securely-generated password. In both cases the mask and password consist of a very long sequence of randomly generated characters. Just wondered if there is an easy way to log in to apps on iphone without having to copy out a long sequence of characters for both email mask and password? Using latest version Sonoma 14.5. iPhone 15 iOS 17.5.1.

In recent Firefox versions, long container names are trimmed to around fifteen letters. Is there a way to disable this feature?

Since containers are named by the same user as the browser, people who want shorter names will name shorter ones by themselves. I wonder who wants this feature.

Version: 127.0.2

I want URLs of a page to stay the same no matter where I scroll, including on Discourse where stopping at a certain comment changes the url to that comment's number. Scroll this page to see: https://meta.discourse.org/t/should-url-change-as-you-scroll/55302

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.

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?
