This useful feature was added to Waterfox 56 in https://github.com/MrAlex94/Waterfox/pull/566 . Could this please be ported to Waterfox 68?
You could try this in a userContent.css file: https://github.com/Aris-t2/CustomCSSforFx/blob/master/classic/css/aboutaddons/addonlists_show_addon_version_number.css
with the xml in the chrome folder too: https://github.com/Aris-t2/CustomCSSforFx/blob/master/classic/css/aboutaddons/addonlists_show_addon_version_number.xml
In my file the rules are within this @-rule: @-moz-document url-prefix(chrome://mozapps/content/extensions/extensions.xul), url-prefix(about:addons) {
...
}
I was able to port the patches from https://github.com/MrAlex94/Waterfox/pull/566 to Waterfox 68, but they're only effective when about:config > extensions.htmlaboutaddons.enabled is set to false. Looks like another patch is needed for when that's set to true, as it is by default in latest Waterfox 68.0a2.
Edit: I was able to get this working with about:config > extensions.htmlaboutaddons.enabled set to true as well. I hope I find the time to get all these patches submitted as a pull request.
@laniakea64 @MrAlex94 for (distant) future reference:
@grahamperrin Waterfox Current shows addon versions in both htmlaboutaddons and classic about:addons. Did you mean to post that in https://github.com/MrAlex94/Waterfox/pull/1194 ?
