Firefox Update 124.0.1 has deleted all my Bookmarks and History - can I get them back?

My Firefox Browser on (Windows 11) updated on 23rd March 2024. Now my History and Bookmarks have been deleted (but not cookies for some reason). yes, it is my correct profile as I checked the dates and also double checked it against a backup I made 2 weeks ago.

Have included an image of my 'more troubleshooting information' details - I'm sure this is supposed to have more data on the page?

If there is no way to recover my hisotry and bookmarks, I see there in my profile folder is a 'bookmarksbackup' folder which contains .jsonlz4 files, one of which was saved on the 21st March 2024. I know book marks are .json files, can anyone tell me how to turn a .jsonlz4 file to a .json?

[Oh, I pressed to add here my 'troubleshooting information' as directed by this forum page and it said it couldn't automatically do it, and when I pressed 'manual', it opened that over this page and so when I pressed 'back' it had naturally deleted this post so I've had to retype everything from memory, thanks so much Mozilla for that. How about a warning that this will happen?]

I go to about:memory > Save memory reports - Measure and save and then view the output, a report called memory-report.json.

In this report I see approximately 30 blocks of text, each of which contains approximately 50 to 100 website URLs. Several blocks contain only porn URLs. I have viewed porn, but only in Google Images; I don't visit the websites.

Why is this information being stored by Firefox?

Note: my Firefox is set to Delete cookies and site data when Firefox is closed. However, even after closing and opening Firefox, all the information is still in the report.

A sample of two of these blocks of text is attached.

Hi. I was just looking at Google Photos on both Firefox and Chrome. Chrome had a bigger picture because the window had only the tabs bar and the address bar, and Firefox has an additional title bar. I was wondering if it would be possible to remove the title bar so the picture on both browsers were the same size?

I can get to log in screen ( Sams' club) but it goes right back to the are you human screen?, 

I can access the website if turn off Adblocker Ultimate. Adblocker appears up to date. When I disable Adblocker there is still a request, but this time a button below to press and hold which takes me to login screen. I can successfully login then. Reporting the issue which began within 5 min of the last Firefox update. I updated 3/23/2024

Recently this month, watching Youtube videos has been a total chore on Firefox. Every so often, when I load up a video from Youtube, I get a blank player with no video in it. Every other aspect of the page template loads properly, but the video is just not there. The only fix for this is to clear my cookies and it's annoying to have to do this every week just to watch Youtube videos.

I've tried using other Firefox Forks, and they've had the same issue. I've used other browsers, specifically Chromium ones, and have not run into the same issues as of yet. I've isolated the problem down to my cookies, as deleting just the cache doesn't do it. Resetting the browser doesn't do it. Clearing my search history doesn't do it. Disabling all my addons doesn't do it. Signing in and out of my Youtube account doesn't work either. Any combination of all these fixes doesn't make the problem go away. The only thing that I've found to work is clearing my cookies.

Is there a way I can fix this? Please let me know ASAP.

When I download PDFs on my MacBook using Firefox (currently 124.0.2 (64-bit)), they are always blank - I have attached a screen shot.

But if I download the same PDF using Safari, it opens straightaway - 2nd screen shot.

Is there something I need to adjust in Firefox to allow PDFs to open?

Trying To Fix The Wrong Time in Firefox Ended Up Removing Firefox's Ability to Display a Player Within a Site if Another Site Has Embedded it.

My Firefox browser did not update with daylight savings (this is my first time being in a country with daylight savings with this PC) and now all in-browser times are an hour behind, which is already really confusing for someone experiencing daylight savings for the first time. Now that I do not have a phone, this went from mildly annoying to really messing up my day-to-day life. As a result, I researched, found and followed this question-and-answer proposed solution to my issue but it didn't work. Now, I've been pushed a step backward because I have also lost the ability to view TV shows and movies on third party websites because the player will not load and a 'Website will not allow Firefox to display the page if another site has embedded it' notice will pop up (image for reference). This is super infuriating due to the fact that my PC is older and genuinely cannot run any kind of chromium browser and Firefox is the only way I can access said third party sites. It would be wonderful is anyone had a solution for both issues; thank you!

When you add a new bookmark to a folder it's added at the end of the existing list.

Is there a way to make Firefox add it at the top of the list, instead?

I found an old answer, but, sadly, the extension granting my wish is no longer.

Also, I already know about sorting, but it's not what I need, because I'm doing a lot of manual bookmarks reordering and sorting will nullify it.

Thank you :)

When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%

Hello! Can you help me sort out a little problem? I am reaching out to seek assistance with a specific issue I am encountering in the Firefox browser.

In my previous browser, when opening new tabs, they were considered active even if I did not immediately switch to them. This behavior allowed me to open multiple tabs, for example, by using the mouse wheel to open several videos from the main YouTube page. Subsequently, when closing the main page, the videos would be available in the order they were opened, facilitating a seamless viewing experience.

Upon transitioning to Firefox, I have attempted to configure the browser to replicate this behavior using the Sidebery extension. However, even with the extension, new tabs are not recognized as active unless I explicitly switch to them, making it challenging to maintain the desired tab activation order.

I have explored various settings and experimented with the Sidebery extension but have not been successful in achieving the desired result. In contrast, the Yandex browser, with the "Switch to the previous active tab when closing a tab" option enabled, behaves in the manner I am accustomed to.

Could you please provide guidance on how I can configure Firefox to consider new tabs active immediately upon opening, regardless of whether I switch to them immediately?

I added pictures to make it clearer what I'm talking about.

Thank you for your time and assistance.
