How can I open an ad on a one-time basis, as if there were an option when right-clicking?
Sometimes we search for something we want to buy. The ad is near the top of the search results and seems to be worth investigating.
But we can't open the ad. Our wonderful ad blocker is, like our guard dog, too zealous sometimes protecting us.
The answer I'm looking for is NOT to go into Settings, etc. That's swatting a fly with a sledge hammer.

According to this article I should be able to activate autofill credit card details in my country https://support.mozilla.org/en-US/kb/credit-card-autofill But the option is no where to be found and in about:config I can see it is restricted to a few countries mine not being one. I can not change the list with countries either, actually I can not change anything nor search in about:config. I am running Firefox 140.0.4 (64-bit) EDIT I made a a master password, which then made it possible for me to edit in about:config. I added my country to the extension and now I can activate it.

Hello,
I am having an odd issue where I see flickering bands of cyan/purple blocks whenever I scroll on a page with some video embeds. At first I thought it was related to refresh rates (240hz) as some pages flickers but it occurs at 60hz as well.
2560 X 1600 Resolution with 125% windows scaling
Steps to reproduce: 1) have settings above 2) navigate to https://store.steampowered.com/ 3) view a storefront with a video embed 4) zoom to 180% 5) scroll up and down past the video

I have a MV3 extension I created that has a popup and data that is stored in sessionstorage and extension storage.
When I use the extension in a private window it does not work because data does not persist between each time I open and close the popup.
This causes problems, for example you have I have to login each time I open the popup, instead of the auth status persisting. It works fine in a normal window though.
Is there anything I can do that allows data for an extension running in an inPrivate window to persist. (Maybe some additional manifest code / changing the browser config)

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.
About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.
Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.
Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!
All the firefox shortcut icons on my desktop have lost their images. Acess to relavent pages still works but no 'pictures'

I've recently swapped to Firefox from Chrome and I've noticed a huge hindrance.
I use a chatroom website and when I swap to the tab and begin to type, the first letter is randomly eaten/won't be entered into the text field.
For instance I was typing the word "What" and the text field only displayed "hat". Or when typing "Either" only "ither" appeared.
I thought this may have been related to a hardware acceleration issue but both settings did not work. So I started to look at Hotkeys but none of them should be interfering.
Some others have stated they have this issue too and I've been unable to find any solution. Any help?

Fix for RangeError: invalid language tag and client-side exceptions in Firefox on Linux
Hi everyone, I was experiencing persistent JavaScript errors in Firefox on Linux when loading certain modern websites (e.g., built with React or Next.js). The browser console showed messages like:
RangeError: invalid language tag: "chrome://global/locale/intl.properties"
A client-side exception has occurred (see the browser console for more information) React error #418 with minified stack traces
This happened even in Safe Mode, with all extensions disabled, cookies/cache cleared, and Enhanced Tracking Protection off. ✅ Root cause and fix:
Turns out the issue was related to missing or broken locale configuration in Firefox. To fix it:
Open about:config
Create a new string entry:
Name: intl.locale.requested
Value: en-US (or fr, en-GB, etc. — any valid locale)
Restart Firefox
After adding this key, all affected pages started working correctly. The invalid "chrome://global/locale/intl.properties" error in intl.accept_languages disappeared as well — it seems that was just a side effect of the missing locale setting. 🔁 Summary:
If you’re seeing RangeError: invalid language tag and React crashes, try adding intl.locale.requested manually. This fixed the issue entirely for me on Linux.
Hope this helps others!

Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.
Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png
I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:
Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png
The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?
