Today I opened my Firefox and all my tabs are gone. I was able to find a backup in sessionstore-backups, but when I renamed it to "sessionstore.jsonlz4" and replaced the one in the main profile folder, opening Firefox still don't gave me any tabs, just the default "new tab".

Usually, when you close Mozilla Firefox or shut down your computer, you can restore the before closed bookmarks while you start again Mozilla Firefox. In my case, Mozilla Firefox automatically updated itself and I could not open again my bookmarks (the history was gone...). I had lots of pages that I still wanted to read and am looking for a way to find them back...

I never delete history! But I noticed this since long time ago, e.g. I want to go on a website - I was recently on (if I closed it already) but it is not in immediate search history - it happened to me multiple times!

Also now: I was searching for one keyword a lot, like 50 times and in history are barely like 7 hits. No idea why it is not there!!!

Please help.

"Pocket List" has disappeared in the drop down menu under the "library" icon where it used to be not more than a few days ago. It's not under the Bookmarks icon, either. the "Pocket" icon is in the menu bar, and I can save items to Pocket, but can no longer locate the page with the articles. "View List" does appear when you click the Pocket icon, but it also saves whatever page you're on whether or not you want to save it.

When holding Ctrl and clicking the back arrow at the top left manually, it opens a new tab with the URL of the previous page, as it's supposed to. But for some reason, when I hold Ctrl and press the back button on my mouse, it doesn't do the same. This is quite annoying, as sometimes I need to navigate back, but keep the current page open as well, and this forces me to move my mouse cursor all the way to the top left and back again

When i click on the google maps icon (google uk home page>dots in top right hand conrner>google maps icon)or type google maps into the search field then click on the google maps link I end up on the Sheffield Hallam University log in page (a bookmark from a while ago). This has started happening in the last few weeks.

If I use Edge then everything happens as expected and google maps opens.

I have tried refreshing firefox and disabling add-ons, neither works.

Using Windows 10 home V20H2, upto date firefox.

For some reason all my toolbar bookmarks have disappeared from the toolbar line below the search box. View Bookmarks Toolbar is checked 'Always Show'. I tried customizing and restoring defaults but still don't show, although the toolbar line disappeared and option was changed from Always Show to 'Only Show In New Tab'

I am using Private Browsing, although it does same even if I don't. So frustrating

What happened? Was a new version released 4/12/2021?

Due to a news story about Google working on a top secret Chinese Military project a few years ago, I have blocked any and all connections and services to Google. I have noticed that FireFox browser shows (very briefly) webpage sites being accessed from within websites that I do visit. I noticed a number of Google Services flashing through the list of site connections. Is FireFox BYPASSING my Firewall settings and allowing Google connections? And If so, are there browsers that do NOT use chromium-based code, that honor my firewall settings? Should I just write my own browser code so I can validate that Google is NOT violating my privacy and committing espionage for the Chinese Military?

Every time I try to open firefox, it instantly crashes. it pops up in task manager but only for a split second (although if my computer has just started up firefox will open for maybe 10 seconds). this is getting really frustrating. No crash errors or reports. I've tried it in safe mode, reinstalling, made sure I have none of the software on my computer which prevents Firefox from opening. Any help will be appreciated :)

Profile migration FF Rapid Release 84.x to ESR 78.6.x (Offline)

Dear all,

I am planning a move towards the Firefox ESR 78.6.x. Currently my customer is using the Firefox Rapid Release 84.x and need your help with the profile migration. The customer has a very isolated on-premises environment and does not allow the users to login into a Firefox-Account. Therefore the settings for Cookies, Cache, History and especially Bookmarks are not synched.

Environment details:

  • Enterprise environment with several tausends of clients
  • All clients on Windows 10 Enterprise between 1809 and 20H2
  • All clients have always the newest Firefox installed currently 84.x

This creates a huge challenge to sync this stuff. Therefore I have now identified the following two options:

  1. 1 Allow the downgrade by using the environment variable MOZ_ALLOW_DOWNGRADE on Windows. For this option I am trying to find the real reason why this "Downgrade-Stop" has been implemented in the first place? What risks in detail do I take to allow this downgrade? Has anybody done this before and do you mind to share your experience here? How many issues did you face and how did you remediate the issues?
  1. 2 Hand over the migration to the users. Copy their current profile to their desktop and ask them to import their bookmarks manually. Not preferred by users and I can't even blame them for.

Is there any other way to automatically sync the profiles from 84.x to ESR 78.6.x without user interaction?

Thanks in advance Amir

I'm working on an addon to automate taking screenshots of lecture slides. I'm using a canvas object to capture and save the file blobs and JSZip to zip everything together and download. But JSZip keeps throuhing the `unsupported file type` error. Even though blobs are supported.

Here's the relevant code I'm using Github File

I've submitted an issue to the maintainer which has some more debugging info. The script in the addon_context has some very quantum behaviour and changes output every time I console.log Github Issue

I'm wondering if there might be a problem on my end, with the way I'm generating and processing the blobs. The same code works in chromium based browser, I'm confused as to what Firefox does differently. Any help would be appreciated.
