You can also Re-Pack the Extensions Crome\*.jar
This saved me also over 1 MB.
Modifying any of Firefox's files and redistributing it is not permitted by Mozilla's trademark policy. I used to recompress the JARs and UPX the EXEs and DLLs, shrinking Firefox to about 8MB, but that's not allowed now.
Sometimes, the impossible can become possible, if you're awesome!
While you can't redistribute TB and FF with compressed files, what about providing instructions on what files to compress after we've installed and how?
And the instructions are pretty easy. Compress all the EXEs and DLLs with UPX using the following options: --best --compress-icons=0 --nrv2d --crp-ms=999999 -k
And then re-zip all the JAR files to use the highest level of compression. I recommend using 7-zip to do this as it has the best compression. If you're using the 7-zip commandline, use: -r -mx=9 -mpass=4 -mfb=255

Thinking back, was there some kind of problem with auto update not working when the files were compressed? If so that may be a good reason to not bother with the compression after all.
The partial updates that just download the differences will fail. But the full update will work fine. At which point you can UPX-compress it again.
