CDNsearch engine becomes my Mozilla search most times itself without my permission . each time i change it to Google search engine but again when i open Mozilla after a while i see CDNsearch engine at first page of my Mozilla. how can i delete it permanently ?

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.

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

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?

I want to be able to select the ai program I would like to use when researching (anything), like I have with Claude, but I don't know how to download the programs and have on the side bar like I have claude. Please help. Also, I can't download Deepseek.

Just in the last week, possibly since a software update, when I click on a link I am diverted to a new website that I did not want to see. The link I clicked also opens, but I have to close the unwanted tab and navigate back to the one I wanted. How can I stop this from happening?

I guess i may have downloaded something not good. Because I keep having to redo the time on my laptop. Then I see under the plugins a warning that it wasn't supported. Like it's not to be trusted. I can't find it now. But I been having to go in and change my time zone every log in just about. Arghhhhh. Help Wizard!
