When i am opening up firefox it loads the last session (as it should), but it opens old cached versions of them all, instead of loading them again. Even when i have cleared all cache and cookies data. Even tried refreshing pages. OPening up in incognito mode nothing works on my PC but the mobile phone on the same wifi network serves the new website ..

Even tried solutions mentioned on [thread ] but it didnt seem to work

Location of the cache/cache2 folder; Windows: *C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>\ Mac: ~/Library/Caches/Firefox/Profiles/ Linux: ~/.cache/mozilla/firefox/

Close Firefox. Open your file browser to the above and remove the folder.

Note that this also can happen if the URL in those tabs have GET data appended (?xxx=xxx) to request a specific page.

Otherwise it should be sufficient to use "Clear history when Firefox closes" to clear the cache.


Try the Firefox version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.
