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.

Hello,

I deployed central management of firefox yesterday and I am suffering firefox hangs on startup (prior to opening any window) after configuration change from pref to localPref. When I kill firefox and run again it usually start normally. Usually one kill is sufficient, but I observed also two subsequent kills are necessary.

I created these files:

/usr/lib64/firefox/defaults/pref/autoconfig.js:

pref("general.config.filename", "firefox.cfg"); pref("general.config.obscure_value", 0);

/usr/lib64/firefox/firefox.cfg:

// This comment is mandatory lockPref("autoadmin.global_config_url","http://www/firefox/firefox.cfg"); lockPref("autoadmin.append_emailaddr",false);

and in the firefox.cfg on a website I have for example: lockPref("network.proxy.type", 4);

when I change the lockPref to pref in this file, everything works normally, but when I change it back to lockPref I get a firefox hang on startup. What am I doing wrong?

Thanks

Marek

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??

Whenever I have Firefox open with certain games, the browser randomly freezes and ultimately crashes. But especially when I have videos running. The game itself does not crash and runs completely fine with no issues.

I have no idea what causes it, and I used to not have this issue at all before. However, I believe it was after I upgraded my computer, which should have no issues with the specs I have.

These are my 10 most recent crash reports: bp-c0eafb4b-6fce-47fa-9e8d-3f9e30240707 bp-dc43a38b-a3df-4231-9e02-ff55c0240707 bp-30bc891a-062d-4f9d-805d-539a20240707 bp-8dda914d-f2f8-4534-83d6-2ac690240707 bp-1858f133-89be-41e0-85e0-501a70240707 bp-e785dd9b-328b-4aec-bff0-002fe0240707 bp-3e7288ac-6d1e-4567-9e95-1a4830240707 bp-2777d574-893b-4e10-a69e-245f90240707 bp-62934e0d-9568-4deb-9354-e7e910240707 bp-2ab1d2bb-d244-4118-a7e1-9d32e0240707

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

For some months now I have been finding that, when I try to log on to the BBC website or the Youtube website using my default browser Firefox I get a timed out message. However, both websites usually open when I try for the second time. This never happened before. For both sites I log on from Windows 10 desktop icons. This defect is now annoying me so much I am inclined to switch to Chrome or Microsoft Edge as default browsers where the problems do not occur. I have tried a number of suggested solutions shown on line but nothing has worked to date. Before I switch default browser I will try further suggested solutions if anyone has any.

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 am a big fan of Firefox Sync in general, and of the "send tab to other device" feature in particular. I have Firefox on all my devices (Android phone, iPad, PC, work laptop and a laptop in a cabin) and while I'm browsing, I do send tabs to other devices a lot, because it's a cool stuff to checkout, but not in the moment, or not in that context: news articles or blog posts discovered on the couch but relevant to work, some items I see in the shop but I want to check dimensions prior to buying, some cool idea to check out while at the cabin, etc. My day-to-day browsing experience relies heavily on that feature.

My issue is that one of the device (laptop in the cabin) is used only randomly, with sometimes weeks between it's turned on again. And after around 2 weeks, that entry disappears from the possible devices I can send the tab too. I do understand where it comes from, as it allows keeping a clean and meaningful list, I can live with that, no worries.

But is there a way to "keep alive" a device beyond these two weeks? At the minimum, something on the mozilla account's device list, like a "confirm still relevant" button next to the "sign out" one.

Thanks Dietmar

I was in the middle of watching the Phillies and the Braves play on Apple TV+ 7/5/24. While watching the game, the screen flashed a message I couldn't catch and that was the end of viewing Apple TV+. From that moment on all that was displayed was the original promotional page (attached) that seemed to have all it's links disabled. After playing with it for awhile with no success I switched to Chrome and the streaming ran okay. I then reinstalled a clean Firefox but I still have the same issue. A dead Apple TV+. I am baffled by this. Need help. Please see attachment. I am running Windows 11

Whenever I log into my amazon account, a windows prompt pops up telling me to use "windows hello passkeys" so I can log into the website using my windows pin/fingerprint. I cannot find a way to stop this from popping up, and I do not want to be bothered by it. Is there a way to prevent this from showing? I can't find any solution online

Similar to what @KW was experiencing here: https://support.mozilla.org/en-US/questions/1392858

I'm also having the same issue. I tried replying to that thread, but it's been archived.

I have two printers that were removed from macOS System Settings in Sonoma 14.5. They are showing in the print dialogue menu in Firefox 127.0.2 on both my laptop (MacBook Air M1) and desktop (Mac Studio).

Rebooting the computer, restarting Firefox, etc. haven't resolved the issue.

/edit: moved thread from Firefox for iOS (iPhone/iPad) to Firefox section as you have macOS.

Firefox's PDF viewer incorrectly applies user-defined font settings intended for HTML pages, resulting in illegible PDFs and requiring time-consuming workarounds.

Key Points: 1. When "Allow pages to choose their own fonts" is disabled in Firefox settings, the built-in PDF viewer renders some PDFs with incorrect fonts, replacing characters with icons and gifs. 2. This setting should only affect HTML pages, not PDFs, as PDFs are designed to maintain the author's exact formatting. 3. Current workarounds (saving/opening PDFs locally or toggling the font settings) are inconvenient and disrupt workflow. (Open a settings tab, navigate to fonts, navigate to advanced, toggle the option, select okay, return to prior tab, reload, view without error, then repeat the process to restore preferred settings.) 4. Users who prefer custom fonts for HTML content are forced to choose between readable PDFs and their preferred web browsing experience.

Background: HTML is intended to decompose information exchange in such a way that the viewer has control of aspects such as fonts; while PDF is a format designed specifically to present exactly as the author intended. The difference is the primary reason an author would choose to use pdf vs html. The issues can be reproduced with B612 and other fonts, in Firefox 127.0.2 and many earlier versions, on github repositories pages that embed pdf files, and most other pdf files opened with the viewer.

Proposed Solution: Implement a separate font control setting for the PDF viewer, allowing users to maintain their custom font preferences for HTML content while correctly rendering PDFs with the author's intended fonts. Or, simply disallow the setting to apply to the PDF Viewer.

Impact: Resolving this issue will significantly improve user experience, maintain the integrity of PDF documents, and eliminate the need for disruptive workarounds, ultimately enhancing productivity for affected users.
