Theme issue with Firefox Snap update to revision 3068

[Little Girl]

Hey there,

I closed Firefox to allow it to update itself when I got the Snap
notification in the bottom right. I ended up with this version:

Firefox 117.0 (64-bit)
Mozilla Firefox Snap for Ubuntu
canonical-002 - 1.0

Here are some photos of what I now see:

As you can see, my bookmarks and settings exist, but the text is
invisible. It appears to be a theme issue.

I would have tried changing to a light-colored theme as a possible
temporary work-around until the issue is fixed, but as you can see in
the second photo, I obviously can't do that.

Also, as you can see in the first photo, I did a search for "ubuntu
firefox snap update bookmarks invisible" just to see if anybody else
is having the same problem. The most recent hit was from last year,
though, so I seem to be flying solo. Anybody else having this issue?

Last, but not least, I'm thinking of doing sudo snap revert firefox
to get the previous last-known-working version of Firefox back from
revision 3026. If I do that, will I have to manually update the
Firefox Snap after that or will it update automatically? When it
updates, if the issue hasn't yet been fixed, will I still be able to
revert to revision 3026 or will the new fall-back be the
currently-broken 3068 revision that's hiding my bookmarks and
settings from me?

I just now did this command to up the number of revisions from the
default of 2 to 4 in the event that the Firefox Snap team doesn't fix
it in the next update or two:

sudo snap set system refresh.retain=4

If this goes on for a while, though, I may need to keep increasing
that number, which seems unreasonable.

Better would be if I could protect revision 3026 from being
destroyed at all. Is that doable? If so, if I occasionally update to
check if the issue is fixed, will revision 3026 remain protected and
available for me to revert to if the issue isn't fixed yet?

Better yet would be a way to revert to revision 3026, back up
revision 3026, update from time to time to see if the issue has been
fixed, and keep reverting back to revision 3026 each time if it
hasn't. Is that doable?
