Firefox Developer Edition - Developer Console is killing my productivity. It started opening in Full screen mode about a week ago and will not exit full screen. I have to F12 and exit developer console. This is a major issue because, I work with the console not docked. Docking blocks my productivity. F11 only puts it into some very weird outline mode where all I see is a rectangular grey outline on my full screen. If I click on it, it repaints the console in full screen. There is no option to drag and expand or contract. Nothing. Nada. Please help. This is my primary browser, er -was my primary browser. I'll continue to work around it until my patience is completely exhausted. Almost there now.

Sorry about the terrible markup on the screenshot. It's hard to encircle a big gray full screen empty frame. Thank you.

I am using Firefox Developer Edition Version: 110.0b5 (64-bit) on M1 Mac running Ventura 13.1.

I am building an webapp some XHR triggering in background but it is not necessary to run the application (running fine on other browsers). But on Firefox Developer Edition, It shows a error window with the message and stops loading the application.

Firefox can’t establish a connection to the server at localhost:4000.

localhost:4000 is the failing XHR request domain. I have attached the screenshot.

How to ignore the XHR failing errors just like other browsers?

The blocks where code should be displayed like on screen and on stackoverflow displayed in a weird manner : replaced with [Object object] i don't have any extensions that might cause that

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

After upgrading firefox to 110.0, WhatsApp web failed to load. I refreshed the browser also as I found one solution on forums, but after QR code came but failed to load the chat.

When playing any youtube video in full screen, all I get is a black screen. Issue does not appear in private mode, firefox developer build or chrome. Other sites ex. go pro media plays videos in full screen without any problems

I'm not sure when this changed, but I can no longer shrink my search bar to make room for more extension shortcuts. There's no double-arrow, no option I can find in customizing (I've tried the unsupported compact thing). I've gotten myself so worked up over this, I'm sure I'm overlooking something obvious.

Thanks for your help.

I have researched and found out many people had this error but no one got a solution, same for me. examples: https://www.reddit.com/r/firefox/comments/sry42x/this_page_is_stored_on_your_computer_icon_showed/ https://bugzilla.mozilla.org/show_bug.cgi?id=1677909 Please help.

Hello,

this problem started happening around 3 or 4 days ago.

Usually, at the end of the day or before I close Firefox, I "delete browsing history" BUT only the "today" history. I know it's a weird habit (lol), but at least it logs me out of all recent browsing while keeping my sessions with older websites active (typically these older websites include stuff that I use frequently like Outlook, Google/Youtube, Twitter & other social media, Spotify, and a few other sites).

The other reason I do this is that I like my "recent history" to be ordered the way I like, so I can use it kind of like a "bookmark list".

The problem: Since about 4 days ago, each time I "delete history", ALL my accounts are signed out. Note that I don't have the option to delete cookies upon closing checked, and whenever I close Firefox without deleting history the sessions appear to be active.

I think 3 or 4 days ago there was a Firefox update? I remember at the time I was shown the extra tab with the release notes, but I didn't pay much attention. However when I noticed the issue, which was the day after, I assumed it was a new feature of the update that caused all these websites not to recognise my browser and thus ask me to log in again.

So just before going to bed, I tried 1) clearing my history for the day as I usually do, except 2) instead of closing directly after, I would go to the sites I want to remain logged in (in this case I just did Outlook, Youtube, Twitter, Facebook, Tiktok and Spotify), log into my accounts, and then close the browser.

So the following day, it worked "as usual"... almost... that is because when I deleted my history of the day, it logged me out of everything again. But in the "recent history" list, it showed the updated list (with the websites I re-logged into the day before).

So I can't guess what is happening, other that something is messing with my cookies each time I delete history. I even went to check manually to see if I still had the session cookies stored in Firefox and it appears to be the case.

Yesterday I also tried logging into a Google, waiting a few hours, and only deleting the history of the past hour, but the same thing happens, I instantly get logged out.

Additional info: when I "delete history" I only check the first five options (those under history) and not the lower two (under data).

Thanks for your help, and sorry for my English !

Since Firefox 109 and 110 also you can not login to hidive.com. It just loads a blank page(empty source) but not logged in. Firefox Developer Edition does work. 110 and 111. Tested on both linux and windows without extensions and tested with tracking prevention turned off. I reported this after 109, but I could not find the report.

This morning, upon opening Firefox, I noticed that I could not scroll through any pages or windows. I turned off scroll lock (or so I thought), and it began scrolling. But then, in all of my other windows, scroll lock was activated. So, I hit my scroll lock button again, and now all other windows will scroll except for Firefox. Is there a setting I need to change?

It appears as if scroll lock is reversed on Firefox vs. all other apps on my computer.

Yesterday, my scrollwheel stopped working on my mouse in Firefox. The mouse moves the cursor fine everywhere, including Firefox, but the scrollwheel only works in other browsers/programs.

my scroll wheel stopped working on firefox, so i launched in safe mode and my scroll wheel was perfectly fine so i disabled all of my addons but it still doesn't work

WIN10 Pro; FF 110.0 (64-bit)

After upgrading to the above version and restarting the computer, I find that scrolling within a webpage no longer works using the mouse wheel. Scrolling can still be done using the vertical scroll on the right.

I've closed the browser and tried again, but the bug remains.

I've verified that mouse wheel scrolling still works by testing on other websites and on documents.

the latest firefox update has disabled scrolling/ i have tried changing the settings in firefox and no changes make any difference. scrolling works on other apps perfectly fine.

Hi!

I can't scroll with the mouse wheel in Firefox. It works fine in other browsers and programs.

If I switch to Safe Mode, the scrolling wheel works. But if I switch back to normal mode, the wheel does not work again.

I tried to switch off and switch on "Use autoscrolling" and "Use smooth scrolling" settings, but it didn't help.

Unfortunately, "Refresh Firefox…" and reinstalling browser completely did not help.

I am at a loss, please help.

My mouse wheel does work when I try to scroll in any page. The scroll wheel works when I am scrolling though tabs but only if I am holding Shift or Ctrl. It also seems to work just fine in troubleshooting mode, but nothing else seems to work. This problem started just after Firefox updated to the newest version.
