Firefox Support Forum

Hello,

Everytime I have to close my pc with updates or if I just close/ restart it or if it crashed and I have to restart everything, all my most recent tabs (when I do restore last session) are gone but I get all the tabs back from weeks or even months ago. It's very annoying especially I do research and study. I really don't understand. It's like going back in time every time it starts again  :( What is happening ?

Thank you for your help ! Vanessa

I have a wordpress blog website. I'm trying to setup google Adsense advertisements on that blog. I seem to have been partly successful because ads are showing in that website when I browse it with the mobile smartphone (also using firefox browser).

But when I try to look for the same advertisements on Firefox, on my laptop computer, the ads are not showing. Instead where the Ad should show, there is a light yellow cream coloured box / space.

I wondered if this is because there might be some kind of automatic ad-blocking on Firefox. But ads of other websites show up fine. Do you have any idea about what to do about this?

I tried whitelisting the site, but then, I'm not sure which site to put it on, and where. What I tried did not work.

I'm using firefox from Debian linux computer. Thanks.K.R

When my pc updated to 107.2.0 esr a couple of websites began to display groups of squares where text and graphics should be... switch back to 106.2.0 esr and problem solved...

I have installed the add-on Clippings. When I wan to modify or organize one of them, it open a new window but I´m not able to see it because is like don´t open it correctly.

One of the help page say: Firefox Desktop encrypts your passwords locally in your user profile directory using a logins.json file. Firefox Desktop uses simple cryptography to obscure your passwords. Mozilla doesn’t have the ability to see passwords, but Firefox Desktop does decrypt the password locally so that it can enter them into form fields.

My understanding is that my local installation uses some auto-generated key to hash my passwords in logins.json. So I established my primary password hoping that all passwords in logins.json will be re-hashed with my new password. But surprisingly ll hashes remain the same. So, where is the security?

Hello All,

After tuning userChrome.css to have tabs on bottom there is a small gap under the tabs towards the page render area. I could not identify the origin of this gap nor which UI object is causing it. Could some expert help remove the gap? Please see attached screen copy and userChrome file below for info.

Thanks, Gert

userChrome is below:

Hi I am using Firefox on Debian 10, and it just plays audio to the pulseaudio server to the right channel. No idea why. Other applications are serving audio in stereo. Any other reports of this or fix?

Hello,

after install Debian 11 I tried to move my profile data (comming from regular Firefox on Linuxmint Cinnamon) as is suggested by https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile, but I found no way to get the job done.

After repeating several times the same procedure, I concluded that Firefox-ESR simply doesn't work with all the regular ".sqlite" and ".json" files comming from regular Firefox.

¿Is any workaround to get Firefox-ESR working with my old data? Is is importan because my old profile holds access data for many differents sites during more than a decade.

Thanks,

After updating to the latest Browser, I have no music controls when I use YouTube Music.
