I installed the English (US) dictionary add-ons from Mozilla Add-ons (English-US Dictionary and US English Dictionary). Firefox confirms they are installed and shows a “Remove” option, but they do not appear in about:addons under Dictionaries or Extensions. Additionally, the dictionary features are not working on webpages—there is no “define” option on text selection, and no dictionary/lookup functionality appears even after double-clicking words or using context menu options. The add-ons only appear as installed on their web pages.

Expected behavior: Installed dictionaries should be visible in about:addons and provide word lookup/definition functionality in the browser. Actual behavior: Add-ons are not listed in about:addons and provide no visible or usable dictionary features on webpages.

Hi there. Ian here. My home page "www.news.com.au" keeps wanting to lock me out due to apparent addblockers on my PC. I am not aware of any that I have installed and can't find a way to remove them or turn them off. I am also not sure if this is a healthy consideration in any case. Can you Help me please.

Hi I use Firefox for years (decades probably). How on earth is it possible that after an upgrade (to 151), I had to manipulate about:config in order to allow unsigned extensions to keep working? Of course, I am not dealing with DIY extensions, but with small and unknown extensions as AdBlocker or uBlock origin... It doesn't seem I am the only one... Any explanation will be warmly accepted...

I have proton pass on an extension on Firefox on my iMac. I want to add the extension to my Firefox on iPad. I deleted Firefox app and reinstalled, I thought I downloaded the extension of proton pass, but I can’t find it. Each time I go back to Firefox and search for the extension it asks me to download Firefox again. I’m in a loop. Would appreciate any help! Thanks!

How to delete the word finder toolbar at the bottom of the browser?

I tried to change the wallpaper but instead found different color settings for the browser. I selected one, but nothing changed, except now I have this word finder toolbar so anytime I type something it pops up and I have to reset focus every time from it back to my computer page. This basically makes my computer unusable.

Extensions, such as Dark Reader, don't work on some designated web-sites. For example: support.mozilla.org addons.mozilla.org accounts.firefox.com

I have a few extensions in Firefox but if I click on the extensions button in the toolbar it now takes me to a Personalize Firefox page where, if I click on Extensions, it only gives me the option of turning them off or on and not to activate or access them. For instance, one extension is Volume Booster which cannot be adjusted on this page. How can I get back to being able to actually using these add-ons?

SerpClix ClickSense could not be verified for use in Firefox. Proceed with caution.

How can I get SerpClix verified? I can't sign in to my SerpClix profile.

What to use to tool for the 3xtentions and hoped to make my searches more valuable to me and 4ich with better info . Not sure where this info is after adding the extentions 5my firefox or how it works . Please help me understand?

So, I tried to delete that post, but it blocked the category of Science completely, so I had to unblock it.

But my point is, Why if I do not want to see this post about Seniors getting bathroom upgrades and I try to delete it does it make an entire category go away? I am sorry, but this is just goofy (trying to be polite here).

This is simply Not about Science whatsoever, that Seniors are getting bathroom upgrades if they live in these zip codes! Also this Same thing has been posted Multiple times in other Categories! Again, this post typically has Zero to do with the Category that it was posted in! I mean Zero Relevance or, more accurately, actually Less than Zero.

So, in the past, I was able to get rid of a post, but now, if I try, it blocks whatever category that the Ad was posted in! What?

Is this now the price of having Firefox? That I have to have postings that I can not either block or delete? Really?

Please explain and tell me why I can not target an individual ad from being posted. Thanks for your time. John D

Windows club downloads to speed up firefox browser: Firemin, Firefox Booster,Speedyfox and Firefox Preloader. Are these offered through firefox settings? Are they safe to use with my Firefox browser?

Upon opening Thunderbird on a Mac (OS 26.5) the program posted a window requesting a password in order to add a new tool to the application. Unfortunately we have lost the password and the program insists it needs the password to continue. An option is offered to 'Ignore', but pressing this button does not launch Thunderbird, rather it sets up some Mozilla 'thingy' operating in the background (the Thunderbird icon in the dock is active) which can be terminated by Force Quitting the process. The thing is, Thunderbird is now unavailable at this point due to the new tool that could not be added to the application.
