As the title says, firefox keeps reenabling delete browser history when firefox closes on its own. After an update yesterday it seems to have reenabled it AGAIN. Back in May near the end of it it also reenabled itself and deleted years of firefox history out of nowhere and I never knew it did so until the next morning when I went to go to a specific part of a site I frequent only to find when typing out the keywords to it, didn't exist.

Found it reenabled itself on its own. Disabled that, and got some semblance of my history remembered again into the system. Made a backup copy of history to some degree into a copy of the places.sqlite file. Yesterday firefox updated again. Closed it last night when i shut off my PC to go to bed and this morning when I opened firefox, I find all my history is gone AGAIN. See delete history when firefox closes is reenabled once more on its own without my permission barely 3 weeks later. I then try to input the backup places.sqlite i made a few weeks ago as well and it gets overwritten by an empty one after I input it back in and open firefox.

I've tried searching for why and how this keeps happening. But every time you search anything on this topic its nothing BUT how to ENABLE the setting, nothing about it auto reenabling and how to stop it or what could be causing it. Web searches are legitimately 0% useful because its just nothing but one sided search results repeating the same thing ad nauseam.

Well, it is quite simple: you upgraded FireFox last night and now I lost all my bookmarks which is horrible and I really do not appreciate what happened and why? It never happened before.....

I am running Nightly 141.0a1 on macOS 15.5 When I two finger tap on a thumbnail image I see the first option is "open link in new tab" and when I choose it, it does as it says and opens a new tab, at the link, in the background. When I need to do this many times, to save a couple of taps, if I Command single finger tap on the thumbnail then on most sites that same thing happens. My problem is that on some sites this doesn't work. What I get is the link opens in the current tab and a new tab is opened in the background but it shows Unable to connect Firefox can’t establish a connection to the server at localhost.

Is this the particular site messing with Command click or is there a setting I can set that fixes this?

Thanks

제목 그대로입니다.

절대로 테마가 아닌 새 탭 페이지 즉 아무 웹사이트도 접속하지 않은 상태에서 이미지 변경하는 방법입니다.

오늘 업데이트가 되었다며 이미지를 변경하라고 해서 아무 이미지를 넣었다가 되돌릴 방법이 없어서 1시간을 낭비했습니다.

절대로 테마아닙니다. 새 탭 페이지입니다. 어떠한 부가기능도 사용하지 않았습니다. 이러한 문제가 아닌지 검토하라는 답변을 줄 경우 무조건 최악의 평가를 내릴겁니다.

Dear Firefox Support Team,

I am encountering an issue where PDF files fail to display properly in Firefox, appearing as blank pages. This problem persists across multiple PDF documents, suggesting a potential browser compatibility or configuration issue.

Request:

   Please investigate this behavior to identify the root cause (e.g., rendering engine, plugin settings, or recent updates).

   Adjust Firefox’s default PDF handling settings or implement necessary fixes to ensure proper PDF display.

Additional Details:

   Firefox Version: All
   OS: windows&mac
   File link: https://res.mdpi.com/data/pharmaceuticals-18-00847-v4.pdf
   Steps to Reproduce: Open any PDF file → Blank page appears.

This issue impacts productivity and user experience. Kindly prioritize resolving it or provide workarounds. Thank you for your attention.

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?

I have just restarted my computer following installation of updated software. I find that Firefox has lost all my bookmarks. Are they stored somewhere, and if so how can I recover them?

I have chosen a theme to set on my browser, from Firefox's addons / themes shop, however when I restart Firefox, the colors from Firefox colors overwrite the theme. It's weird because when i got to the themes page it still shows as enabled, and I need to disable and enable it again. I'm using Firefox Browser 139.0.4 (64-bit) And Windows 10

Hi,

I have tried to sync between my two computers, but it did not work out well:

e.g when I click on ‘show more bookmarks (>>)’ on the right side of the screen (next to Other Bookmarks) I get - Firefox is not responding and I have to click on

-> Close the program.

If I click on -> Wait for the program to respond - Firefox never responds! And before I click on -> Close the Program - my keyboard input is totally erratic!

This occurs on both computers! - what can I do…..

I have therefor on the computer I want to be on the receiving end:

- deleted: History, Downloads and Tags and All Bookmarks - Cleared browsing data and cookies - Closed all open tabs

And now I am Signed in with Syncing; ON - on both computers again.

But I have not checked any of the check-boxes in ‘Manage sync…’ - ‘Manage what syncs on all your connected devices’ i.e. Bookmarks, Passwords, settings, History, Payment methods, Open tabs, Add-ons

Why is there no check-box tag groups!

What do I have to do on my SOURCE compute and on the DESTINATION computer for - a one way sync of everything?

Best regards, Einar

After Signing in I was presented with the following, and I chose Not Now
