Firefox has signaled they're now also going to support Manifest V3, by the end of 2022: https://blog.mozilla.org/addons/2022/05/18/manifest-v3-in-firefox-recap-next-steps/
It would be nice to not have to maintain separate versions of the extension for Chrome and Firefox.

Hi, the Due Date set for this open task passed a while ago.
Could you please either update or reset the Due Date (by clicking ), or set the status of this task to resolved in case this task is done? Thanks!

Hmm, I expected bug reports about stuff breaking by now... Either people are using older versions of Chrome, or Chrome hasn't removed support yet.
I'll investigate, as it appears the extension still works. I have some spare time, I'll see if I can implement this.

I'm using Chrome 111.0.5563.64 (Official build) (64-bits) on Debian 11, and the extension still works. I get the readonly warning when enabled, so that functions as expected. The browser console doesn't show anything either.
Ah, so some quick googling pointed me to https://developer.chrome.com/blog/more-mv2-transition/, which states the removal of v2 is happening somewhere around version 112 to 115, depending on the release channel. Soon, in other words. Publishing of v2 extensions is still possible until June 2023, so I'll set that as the due date. Given that I have the equivalent of a bank holiday coming up next month, I'm sure I'll be able to meet that deadline.

Unsurprisingly, I've hit a snag. Also unsurprising, it has to do with the limitations of manifest version 3 in Google Chrome; the fact that regular extensions are no longer allowed to use blocking web request modification. Only statically defined modifications to headers are possible, which is useless to us. At this point the extension is heading for certain doom: when the deadline passes, it will be unusable in Chrome. Firefox doesn't have this issue, because they still permit blocking web request modifications in v3. The unfortunate part is that it is only supported in version 109 and above, and the ESR bundled with Debian Bullseye is too old for that.
I've uploaded https://gerrit.wikimedia.org/r/c/performance/WikimediaDebug/+/897965 for others to look at, but consider it abandoned.
