Dear Firefox, My mouse is not doing the usual function. The right click is giving me different options like translate the word I highlighted or search the meaning. I just need the right click to copy. How did it even changed without my knowledge. Thank you, Alice

Bei jedem Öffnen von Thunderbird bekomme ich mindestens 200 mal diese Fehlermeldung angezeigt. ich habe mit Mail Merge gearbeitet, jetzt jedoch deinstalliert: Dennoch permanent die Fehlermeldung. Wie kann ich den Fehler beheben? Siehe Screenshot

I have Bing as my homepage, but on one computer I have a very annoying problem. I click on the settings to turn off 'Show news and interests' and 'Show trending on Bing', but the next time I come back to the homepage these settings have turned themselves back on. What do I have to do to retain these settings?

Recently moved to Linux Mint with Thunderbird 140.5. It's a new experience. Thunderbird has downloaded all my emails and folders from my Outlook.com account. Can send, receive, edit emails no problems and all is visible from Outlook client on other machines. Thunderbird does not show my calendar entries or contacts. I do not wish to import from Outlook as I would like to access my Outlook.com from several locations. Been through online Help articles. Nothing seems to work. Have installed TbSync and Lightning Calendar Tabs add-ons with default settings. I have tried suggestions provided in this Mozilla Support. Other forum suggestions don't seem to relate to the version I have.

I'm sure it is something simple as everything else I have done with my new environment is working wonderfully. Thanks in advance.

What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

I’ve developed a Firefox extension similar to the RankingsFactor SEO Chrome Extension, which analyzes on-page SEO elements such as meta tags, headings, links, and canonical tags.

The core functionality works fine in Chrome, but when I ported it to Firefox using the WebExtensions API, I’m facing permission issues while trying to access or read the page content (DOM).

Here’s what I’m trying to do:

Inject a content script to read <meta> tags, headings, and links.

Display this extracted data inside my extension popup.

However, in Firefox, the script doesn’t seem to have proper access to the page DOM — even though I’ve included "permissions": ["activeTab", "tabs", "<all_urls>"] in manifest.json.

I’d like to know:

Are there any additional permissions required in Firefox to read page content?

Does Firefox handle activeTab or content_scripts differently than Chrome?

Is there a specific event or user action needed to grant temporary permissions?

Any help, code examples, or guidance on fixing these permission restrictions would be appreciated.

Hi,

I am in the UK I want to access channel t catch-up service and get a request to disable the ad-blocker.

I have no idea what the icon looks like or how else to mam=nage it. I didn't know that I had an ad-blocker.

See screen dump of the FAQ

Help most welcome

Thanks

Hello, I have the F-Secure password manager on my PC. Synchronization with my smartphone is also working fine. But it doesn't work in Firefox Android. I can't set up an extension for F-Secure. Thank you very much for your help, Peter

This topic was already dealt with at https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://support.mozilla.org/si/questions/1491724&ved=2ahUKEwjh3JWX1KSRAxWDyMkDHYXfDf0QFnoECBsQAQ&usg=AOvVaw2Zp2I2jgPnZ9gkSf5UgMGS. The solution given there was to change extensions.screenshots.disabled in about:config.

Unfortunately, my Mozilla Firefox (ver. 144.0 (64-bit)) doesn't have extensions.screenshots.disabled. So what now?

All my addd ons (Ad Blocker, DuckDuckgo privacy essentials, Sound fixer, To google translate) are all turned on but they are all disabled. Maybe since this last update?

I am on a Windows 11 machine. Lastpass extension for the Firefox browser does not maintain my vault data. I have to refresh each time I go into the browser. This just started a couple of days ago. Perhaps after installing a new Tmobile gateway? Ideas on how to address/fix?

It's possible that I misread the documentation, but I looked for a response to this question for 20 minutes, and I couldn't find a 100% clear answer about my question when it comes to Firefox for Android.

Say I install an extension on Firefox for Android, that requires permission just for a specific website (e.g. let's say, for example, it's an add-on for blocking automated translations on youtube, with permission scope restricted to youtube only). Later, the extension automatically updates itself (as apparently, it's not possible to disable automated updates for extensions on Firefox for Android). The update now includes a larger permission scope, for example permissions for some other websites, or even the permission to "Access your data for all websites".

My questions are:

Is this scenario possible? If so, will I be notified of the changes in permission scope? Would I be able to block the update in this case?

Thank you.
