Firstly, big thanks @JustOff for the great extension that makes the web usable for folk who prefer to surf without excessive amounts of blinding white everywhere!
It seems there might be an issue on PM 28.0.0 with both Advanced Night Mode 1.0.8 + uMatrix (any version from 1.1.4) installed. Testing on a brand new profile to debug the issue, a minor glitch is occurring on new windows. The PM menu is appearing at the left of the Tab Bar even when the full Menu Bar is also enabled.
* Loading PM 28.0.0 initially brings up a new window as normal:

* Opening an additional new window (ie. Ctrl+N) results in the following instead:
PM28-ANM-uMatrix.png
This is in a profile with the full Menu Bar turned on, meaning that new windows shouldn't have the drop down PM menu at left of the Tab Bar. It is interesting that the glitch can be fixed (must be done in each new window, however, so only a temporary fix each time) as follows:
1) Right-click blank area of Tab Bar
2) Uncheck Menu Bar
3) Right-click blank area of Tab Bar
4) Check Menu Bar
After these steps the Tab Bar in the additional new window looks normal (ie. no additional menu at left) as per the first picture above.
Additional tests done include a new PM 28 profile with only uMatrix 1.1.4 installed (no other extensions at all) and the issue did not occur. The issue also did not occur in a PM 28 profile with ANM 1.0.8 installed but
not uMatrix, even in combination with about 20 other regularly used extensions. Thus it appears to specifically be a PM 28.0.0 + ANM 1.0.8 + uMatrix issue.
Versions of uMatrix tested include 1.1.4 (last official XUL version), 1.1.18 (last XUL version easily built from source using "tools/make-firefox.sh all" command), 1.2.0 (with patch kindly provided
here), and even 1.3.2 (last version successfully built by myself using basically same 1.2.0 patch -- versions from 1.3.4 onward all have display errors even after the patch and don't work correctly).
Finally, the issue described did not occur on any PM 27 version including 27.9.4 with ANM 1.0.7 or 1.0.8 and any of the uMatrix versions also installed. In case it matters, though probably not for these two extensions, some tech details: OS = Ubuntu 16.04 derivative (Mint Serena); Desktop Manger = MATE; Window Manager = Compiz).
Hopefully someone will be able to figure out what interaction between PM 28 + ANM + uMatrix is causing this glitch. Though it is pretty minor really and everything else about PM 28 seems great so far (in the first day of testing only, but looking good)!
