Where do extensions generally store their data. EG Tab Session Manager. In this case there is a tab for storing backups but nothing is said about where the basic data is stored.

I assume it's somewhere in the profile info, but the files generally have impenetrable names. Most of the extension devs aren't easy to contact.

MacOS 15.8.3. Firefox 160.0

Hi everyone!

I am using the add on 'sidebery' for vertical tabs.

Recently I updated to FF 157.0 and saw this annoying part in the sidebar (as seen in the image attached "started like that...")!

I didn't ask for taking up THAT much space in the sidebar area that could fit almost TWO vertical tabs in it! Can you (or I?) somehow make it go away completely?

The userChrome.css 'trick' with sidebar-header #sidebar-box {

  display: none !important;  

} didn't do it.

...

So...Fast forward and another update took place (158.0) and looking at the attached image ("now..."). That space needs to be GONE for good. Like it was before. And not with a label tacked on top. :)

Can you make go away?

Cheers!

I use Firefox and Adblock Plus on my laptop. I have it turned off for Fox News. I am getting a banner that says "allow adds on Fox News". To work around this problem I turn Adbloclk Plus on and off three times then I get a banner that says "Continue without Supporting". This only works for three or four articles and the cycle starts all over again. Can anyone help with this problem?

I have NordPass running in my Google Chrome Browser. I would like to have NordPass also running in my Firefox Browser. I would like NordPass in Firefox to make use of/access all the data already stored in the Google Chrome NordPass program. How do I accomplish this?

I'm trying to install a recommended add-on called Ghostery, but I keep getting the message, "Download failed. Please check your connection." This is happening with all add-ons even though I am connected to the internet.

Today, while I was using my browser, I got notifications that several extensions I regularly use had been uninstalled - and that was only from the extensions which usually provide that info on being uninstalled!

Uninstalled were: - Tampermonkey - Browsec VPN (what I use when Mozilla VPN is unstable) - Stylus (which I use to make several sites usable/navigable) - Tumblr Outbox (wiping all saved outgoing ask messages I'd previously had saved!) and

Worst of all - ONETAB

Which had ~1000 tabs saved in it!

I couldn't find a way to recover OneTab as-was, so I was left with the option of reinstalling it which, according to the Devs, means that any recoverable data IS lost at that point.

So I want to know which bright spark's idea it was to randomly uninstall people's extensions for no given reason, especially when they're ones for which recovery is difficult to nigh-impossible.

I want to know who did this, why they did this, and what can be done to fix it, because a number of those saved tabs were for work. Others were for personal projects. Usually Firefox bundles this kind of thing in with an update and it usually fixes if you reload the browser - no dice today. So I want to know if I can just expect this kind of meddling going forwards or if I should start searching for a different browser entirely.

I came to Firefox to avoid Chrome nonsense. If I'm going to experience this, why would I continue to pay for the VPN or use the browser?

Using Win.11, FF 160.0 Bitwarden 2026.10.2 Malwarebytes 3.3.9 The above 2 extensions do not play well together. When Malwarebytes is active, Bitwarden does not operate properly even if Bitwarden.com is excluded from Malwarebytes. Sometimes, Bitwarden does not open at all, or I get the uploaded image.

I have been trying to use Rakuten which has been working fine. For the last few weeks I have been getting this message for all web sites I visit: Your ad blocker is working too hard! To earn Cash Back at [all web sites I visit], disable your ad blocker and refresh this page.

Hello, I am trying to find extension " IBM Security Rapport " for firefox. It's now showing up on the Firefox extensions list. I appreciate any help you can provide.

thank you

I am not sure what I removed from Firefox settings. It has affected how somethings appear on screen. Here is an example of the what my facebook texts look like now. If anyone know what I removed and how to reinstall it I would appreciate it.

I think it might have had to do with image replacement page. I remember 3 objects on the page and I deleted one, I remember it having show an X logo like musk revamped twitter.

Any help or suggestions are appreciated

I am on a tech page, i,e,. on the wiring of a computer fan speed control. Immediately there is a popup of pictures or even a schematic in centre screen. No movement on screen is allowed. Hitting Return or Space bar makes the popup go away, but as soon as I move the page, the popup (same one each time) constantly keeps returning and i cannot read the article. So the page is totally worthless and frustrating to me.

Is there a way to suppress the popup?

I have hundreds of bookmarks and I'm looking for a simple extension to check if the particular bookmark is still active and something that can download bookmark icon. I don't need some elaborate, overbuild extension, just a simple thing that can do just those 2 things. Nothing else. Any recommendations?

Please answer my question above: "Is there a Firefox extension that would block Washington Post popups at bottom RH corner of pages?" THANK YOU! P.S. I have been enjoying Firefox for Mac as my default browser for nearly 20 years.

I need a simple explanation about this and what to do: "Allow RYD to show dislikes and count your votes." I know you have a support multi page explanation but it looks way more complex than I am able to get into.
