There's just one thing that worries me in general about the multi-browser support: there should be one bucket for each of Chrome, Chrome Beta, Firefox, Firefox Nightly, Brave, Opera, etc to prevent issues where there are two instances concurrently (still achievable by using profiles or portable installs, but far less likely).

Maybe worthy of an issue though?

@ErikBjare Yeah, I wrote about that in the forum thread. We currently just check the useragent for firefox/chrome but that should be possible to extend.

@ErikBjare Updated, now actually works. Tested with Opera with the following aw-watcher-web patch
ActivityWatch/aw-watcher-web#37

Together with the changes to choose all buckets in #141 by @nicolae-stroncea it works very well with running firefox, chrome and opera all with watchers running and visualizing them summaried together.

@johan-bjareholt Didn't we talk about aw-watcher-web-chrome becoming aw-watcher-web-chromium for Chromium? If so shouldn't we split the appnames['chrome'] into chrome and chromium variants?

@ErikBjare That is impossible to know, this is the useragent for Chromium on Linux

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.100 Safari/537.36

No mention at all that it's Chromium.
