Solving the recent Firefox ESR problem, with the Expired Extension Signing Certificate.

One of the problems that befell (almost all) Firefox users, midnight from May 3 to May 4, 2019, was, that many extensions which we had installed had suddenly become deactivated because an Intermediate Certificate used to sign those extensions, had simply expired. Apparently, somebody overlooked that status of the certificate in question.

To remedy this situation as quickly as possible, Mozilla offered to publish a “Study”, which is a kind of project that Firefox users can subscribe to, and the purpose of which usually is, to allow Mozilla to conduct experiments on users’ browsers. This study had as purpose however, just to install a renewed certificate.

One important piece of advice is, ‘If you are still experiencing this issue, Do not try to uninstall and reinstall the extensions. Doing so would delete all the data stored with the extensions, while simply to have them disabled, and then to have them re-enabled, will allow most extensions to keep their stored data!’

Therefore, to receive this fix, what Firefox users were advised to do, was to go into ‘Tools -> Preferences -> Privacy & Security’, and there, to Enable Studies. The problem which I experienced myself was, that this advice was not narrowed enough, for Linux users with ‘Firefox ESR’. First of all, the Linux versions of Firefox have their Preferences sub-menu under ‘Edit’, not under ‘Tools’, but that was the least significant problem. What was worse was that, under my Linux distribution, the option we were advised to check was greyed out, and could not be checked:

Because as of this time, under Debian / Jessie as well as under Debian / Stretch, the official fix for this problem has been pushed through the package repositories, it’s no longer advisable by any means to apply the workaround described here. However, the update under Debian / Stretch was a bit slow in coming, for which reason this workaround served me well.

(End of Edit.)

However, I was able to get this feature of Firefox ESR to work anyway. And what follows is how I did that…

Firefox Quantum now available under Debian Linux

There has been an ongoing subject, concerning Debian distributions of Linux, and Firefox upgrades. The Debian users, at least if they were restricting themselves to standard repositories, were being held back to a version of Firefox, which was referred to as Firefox-ESR, which stands for ‘Extended Support Release’. This release was receiving regular security patches, but no major upgrade in the version number, which meant that it was always at some sub-version of Firefox 52…

Well only yesterday, my two Debian / Stretch computers, which I name ‘Plato’ and ‘Klexel’, finally received a much-anticipated upgrade to Firefox Quantum, which is also known as Firefox-ESR, v60…

I am happy with Firefox Quantum, but perhaps only, because certain earlier, unstable versions of it, never made it into the Debian repositories? There is one observation about this updated browser-version which I need to make. As was announced, Mozilla dropped support for the old, ‘Netscape Plugin API’, which I had still been using to custom-compile plug-ins. Instead of using this API, up-to-date developers are being asked to use the ‘firefox-esr-dev’ package. but alas, the last time I checked, this package was not up to version 60… This package was still at version 52…
