Invert Colors 0.1.6 sometimes non-effective with Firefox ESR 52.9.0 and Waterfox 56.2.5

[grahamperrin]

Tested at http://www.ianbicking.org/blog/2014/09/professional-transitions.html with:

• Firefox on (Tier-3) FreeBSD-CURRENT
• Waterfox on (unsupported) FreeBSD-CURRENT.

Version 0.1.6 of the extension seems to work with Firefox, but not with Waterfox.

Comparison

Monochromer by @xia-sava is effective with Waterfox 56.2.5, so I imagine that Invert Colors could be enhanced to support Waterfox.

Waterfox is not a supported platform, I do not have time to maintain support for multiple browsers.

You are welcome to fork and maintain an add-on for waterfox.

Thanks, from https://addons.mozilla.org/addon/invert-colors/reviews/1241170/:

… do not really know why you would expect it to be supported.

Not necessarily supported, but logically I did expect it to work because version 0.1.6

Works with … Firefox 42.0 and later

– and Waterfox 56.0 was based on Firefox 56.0.2.

Testing now with (outdated) Firefox ESR 52.9.0 on (outdated) Mac OS X 10.9.5, current version 0.1.6 of the extension is sporadically effective. Sometimes does work at a page, sometimes does not work at the same URL.

My first impression with Waterfox was that the extension was simply not effective but now, I find it similarly sporadically effective. For example:

I'll add some detail from the Firefox environment …

With a less heavily extended Waterfox profile, the browser action (toolbar button) was, loosely speaking:

1. consistently, repeatedly effective at https://www.waterfoxproject.org/en-US/
2. not immediately effective at e.g. https://github.com/padenot/up-to-eleven#readme – need to reload for inversion (or reversion) to take effect
3. not effective at e.g. https://addons.mozilla.org/en-GB/firefox/addon/up-to-eleven/ – expected, given Mozilla's CSP
4. then no longer consistently effective at https://www.waterfoxproject.org/en-US/ – as with the GitHub example, it became necessary to reload.

I wondered whether restarting the browser would restore effectiveness for the https://www.waterfoxproject.org/en-US/ example, it did not.

In the browser console, when the browser action is not immediately effective:

TypeError: browser.sessions.setTabValue is not a function background.js:18:5

browser.sessions.setTabValue(tabId, "invertColors", state).then(nullFunc(), nullFunc());

– and:

Error: Missing host permission for the tab

It looks like this API is not provided with Waterfox.

You might want to try version 0.1.4

[grahamperrin]

Sorry for the late reply (catching up with things after a few weeks without a proper computer).

Yep, 0.1.4 seems fine, so far. Installed a couple of hours ago.

Examples element-hq/element-web#7578 (comment) and below:

– combined with ReFont.

https://addons.mozilla.org/addon/invert-colors/versions/ appears correct:

Thanks!
