@MatzFan, hello! We were able to reproduce the context menu issue, but we couldn't reproduce the user rules one. Can you help us out?

Please do the following:

1. Download 3 builds of the AdGuard browser extensions at: https://uploads.adguard.org/firefox_4.3.64.zip https://uploads.adguard.org/firefox_4.4.18.zip https://uploads.adguard.org/firefox_4.4.22.zip
2. Extract files from firefox_4.3.64.zip to any folder.
3. Go to about:debugging#/runtime/this-firefox in Firefox browser.
4. Click 'Load Temporary Add-on...' and choose to open manifest.json file from the firefox_4.3.64 folder.
5. After installation of the extension please add and save the following rules to the User rules:

||example.org^$script ||ads.example.org^$third-party ||example.org/ads/* ||example.org^$subdocument example.org##div#ad_banner example.org##.advertisement example.org##.social-buttons example.org##h2:has-text(ads) example.org##+js(set, open, noopFunc) example.org##+js(setTimeout-defuser.js) example.org##+js(set, location.href, '') example.org##+js(noeval.js) ||example.org^$media example.org##div:has-text(subscribe) ||example.org/tracking/*$third-party

6. Replace files from firefox 4.3.64 folder with files from firefox_4.4.18.zip archive.
7. Go to about:debugging#/runtime/this-firefox and click 'Inspect' to display the console of the background page and 'Reload' on AdGuard AdBlocker tile to update the extension.
8. Right click on any entry in the console and click 'Save All Messages to File' (you can use this page for the reference)
9. Check whether user rules are present, if they're not please attach the logs to a comment in this issue. If they are, then follow the 6-8 steps but replace 4.4.18 extension with 4.4.22.
