I'm at a loss for words here. I have a website I frequent and it has a really annoying behavior. I'm a developer so finally I mustered the strength to do something about it. I googled how to create an extension in Firefox and within 5 minutes I had a working extension that solved their annoyance. However, I can only load it temporarily. If I close Firefox, it goes away. When I try to actually install it, it says I need to have it signed. I have now spent the better part of an hour trying to find out how to self sign it. I refuse to believe that I have to submit this to Mozilla for me to be able to install my own code. Can someone please send me in the direction of how i self sign and install my own extension. I have no intention of publishing, I only want to run this for myself.

When using Netflix in full screen there is a slim transparent bar which shows my desktop at the top of the frame. It was not here a few days ago, i might have updated since then. It does not appear in YouTube full screen but i have not tried any other websites to see if it's there. Restarting my system and Firefox did not resolve the issue. Is there any way to fix this, or do i have too wait for a bug fix/the problem to be identified?

As I understand, `autoconfig.js` (with `firefox.cfg`) can be used to have JavaScript run during startup to control Firefox's UI elements.

I have set up `autoconfig.js` in my `/usr/lib/firefox-developer-edition/defaults/pref` folder (I'm on EndeavourOS Linux). As instructed here, I've already put the two required files, `autoconfig.js` and `firefox.cfg` in their correct folders (`/usr/lib/firefox-developer-edition/defaults/pref` and `/usr/lib/firefox-developer-edition` in my machine).

The file `firefox.cfg` contains the following code:

 //
 (() => {
   var tabbar = document.getElementById("TabsToolbar");
 })();


However, every time I run Firefox, this message will appear:

 "Failed to read the configuration file. Please contact your system administrator."


If I empty out the `firefox.cfg` file, Firefox will run normally without showing the error message. It will also run normally if I just have something like this in the file:

 //
 (() => {
   var testVar = "";
 })();


I don't understand why the JavaScript code can't access the Firefox UI elements through `document` or `window.document`. If `autoconfig.js` isn't build for that, what should I use to change my browser's UI elements through JavaScript?

Thank you.

Hi,

For as long as I can remember I've been able to ctrl + click in the "text area" beneath the link in DuckDuckGo search results and Firefox would open a new tab and switch to that tab automatically; but if clicking on the link itself Firefox would open the link in a new tab in the background. This was a priceless feature until today with the 123.0 update. Now ctrl + left click in the text area opens a new tab in the background but does not switch to it. I've been able to confirm this is only effecting v123 on all both linux and windows.

Hoping somebody here might be able to suggest to development returning this feature back to Firefox or help me figure out a way to set this option manually myself.

Thanks!

On bootup firefox opens a single window which says the following:

Sorry. We’re having trouble getting your pages back." We are having trouble restoring your last browsing session. Select Restore Session to try again.

The restore function succeeds in restoring 6 windows from the prior session, but this notice keeps appearing on every bootup.

Here are a few relevant details from about: config

  • browser.sessionstore.max_resumed_crashes (is set to 1)
  • browser.sessionstore.resume_from_crash (is set to true)
  • No 3rd party third party cleaning software
  • Two extensions, tab stash and tree tabs
  • There are no entries in about:crash for this event

Have been using Firefox from 2004 with 5-10 open windows which appear on bootup as they existed from the prior session. This is the first occurance of this error. Appreciate your support. Here are a few system details:

1.) 28gb ram 2.) Linux ~ LMDE 5 (Elsie) 3.) Firefox ESR 115.8 (oesr) 64 bit.

Hello,

Like I suppose any user of older systems (Macs...) that cannot be updated to a newer OS version and thus locked-in to an older Firefox browser I received an email today:

"Don’t stop the sync. Upgrade your Firefox before March 31st."

Why, why, why??

Why would Mozilla take away this last little bit of usefulness after already having abandoned all updates to the browser itself? Why actively "fix" something that ain't broke in a why that does actually break it?

And don't give me the sacrosanctuous security argument please ;) - I never synced sensitive information, not even my browsing history. If security *is* the reason it should be hardly more difficult to disable/disallow just the syncing of that information at the server end. We're clearly speaking at a change on that end anyway, otherwise everyone NOT running the very latest version would be urged to update, not just users of v78 and older.

Anyway, I'm sadly aware of the fact this little rant or even a concerted action isn't likely to change anything, so what options are there? Any suggestions for browser extensions that provide syncing of bookmarks and maybe open tabs or even browser preferences?

Thanks!

PS: I'm posting this from another older system currently still running a Ubuntu 14.04 version that is in fact hardly younger than my Mac's OS but still enjoys Firefox updates...

FF version Extended Support 115.70esr (64bit) I have set /General/Startup/"Open previous windows and tab" - FF does not restore. It worked as expect before I upgraded opsys (Opensuse15.4 to Opensuse15.5).

Please note: I AM NOT TRYING TO RECOVER FROM BEFORE THE UPGRADE! I am trying to get FF working normally (for me) with my usage and history SINCE the upgrade.

After reading https://support.mozilla.org/mk/questions/1407888 I believe I have tried everything there. FF sometimes restores one single historic tab, sometimes it comes with with one single tab opened to my default page.

1) "sessionstore.jsonlz4" did not exist in the main profile dir. (It does not because I followed instructions in the link above to copy it there and try again).

2) I do have a session file, found in sessionstore-backups dir , displayed with this recommended online converter/translater "https://www.jeffersonscher.com/res/scrounger.html"; it shows the expected windows and tabs.

3) Starting after copying the "sess...jsoniz4" file into the main profile dir, I get one window with one tab displayed; I had about 4-5 windows and 15-20 tabs open when I last closed FF, although when doing research, I often have a 10-dozen windows with 100+ tabs.

4) The History menu does not show a "Restore..." option at all. In the window that did open with a historic tab, the History/RecentlyClosedTabs contains a list of plausible sites, about 10, which may be correct for that window. But there were certainly many that were actually open at the time I shut down FF and the window has only opened one.

Thank you for any help here. Rufus

I have enabled privacy.resistFingerprinting in Firefox. I have also set my default zoom level to 133%

When I open a website (e.g. https://github.com/), it is zoomed to 133% as expected. If I then navigate to a page on that website (e.g. https://github.com/pricing) using the menu at the top of the page, then the new page is still zoomed to 133%. So far, so good.

However, on the new page (https://github.com/pricing) if I increase the zoom over 133%, then navigate back to the original page (https://github.com/) using the menu at the top of the page, then my zoom level is reset to 100%.

Is this expected behaviour? I would have thought that the zoom level would be reset to 133%, not 100%.

I found this, which seems somewhat related: https://bugzilla.mozilla.org/show_bug.cgi?id=1609880

Tomorrow I will help a friend update their unsupported Linux OS to the most current version of the OS. The present version of Firefox is 88. Firefox could not update I assume because of the age of the OS.

My concern is porting everything correctly from the old to the new version of Firefox. If I setup sync, will it restore his passwords and add-ons in addition to his bookmarks?

If not is there a good way to do it?

I'm using a Hotspot provided by Cisco in a library and when first connecting to the Wireless network, Firefox prompts me to login to network in order to have Internet access (expected and works fine). However, once the time session expires Firefox will sometimes prompt again to login. When this fails and internet access is abruptly ended, I've to reconnect to the Wireless network and have Firefox prompt to login.

This is a security vulnerability as someone could advertise the BSSID of the router and have victims connect to their Hotspot instead of the true one.
