Because some Flash Player issues I should try FF x64 version. How could I check which add-ons from the ones I have will run on it? I use many important add-ons and don't wanna lose them. Also if such check is impossible or for sure I can lose add-ons then can I install FF x64 separately from my current x32 one?

Chosen solution

Add-ons encompass plugins, extensions, themes, & search plugins.

Extensions aren't 32-bit or 64-bit specific, the 'thing' is whether a specific extension is e10s compatible or not. https://www.arewee10syet.com/

The Flash and Silverlight plugins are compatible with Win64-bit Firefox, but no other plugins.

Yes, I know that from another old question. I meant the add-ons, not the plugins.

To further answer what the word Addons or Add-ons refers to see https://addons.mozilla.org/faq

The word Addons or Add-ons was started in use by Mozilla back during Firefox 2.0 / 3.0 days in which the separate things were then grouped together under one word. This did not make things easier to do support.

Some extensions are OS specific like the toolbar Extensions provided by antivirus clients on Windows which needs to be updated for each new major Firefox Releases.

Yes, I call Extensions add-ons as they are like that here in the site. But not in same browser, I know it. So thank you that understood me correctly and told me Extensions don't depend from browser being x32 or x64.
