Zoom changes to default when navigating away from the page
Problem: Page zoom level spontaneously changes to default when I switch to another tab or follow a link to another page.
Steps to reproduce.
1. Open two tabs. 2. In the first tab go to https://softwarefoundations.cis.upenn.edu/lf-current/Basics.html 3. Press Ctrl+= three or four times to increase zoom level. 4. Switch to the second tab and back to first. Alternatively, search for the string "n:nat", click on the link "nat" and go back.
Expected behavior: zoom level is the same as before switching to the second tab. Actual behavior: zoom level is changed to default.
This happens on a minority of web pages but still quite frequently. The same behavior occurs in safe mode.

Does toggling browser.zoom.siteSpecific make a difference?
You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.
- browser.tabs.remote.autostart = false
- browser.tabs.remote.autostart.2 = false
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
Thanks for your reply.
Setting browser.zoom.siteSpecific = false does help: the zoom is not changed. However, I like that Firefox remembers zoom on sites I visited previously, so I wouldn't want to set this to false.
Setting browser.zoom.full = false does not help. The zoom is changed. Also, I like that the whole page is zoomed and not only text.
browser.tabs.remote.autostart = false: This was the default in my case. Setting it to true does not help, either.
Setting browser.tabs.remote.autostart.2 = false does not help. The zoom is changed.
I found another setting: browser.zoom.updateBackgroundTabs. Setting it to false seems to prevent zoom from changing. I'll see how it goes.
