I have the latest version of Firefox on my Mac with macOS Tahoe latest version. I open a new Firefox web page, all is OK BUT suddenly without my interaction it “zooms” to an unusable size. I tried to reload but, this makes no difference. The only solution is to open a new Firefox web page. I went to the community support page and typed in the problem. I then tried “Share Data” > this opened a new page. I then discovered that my input on… https://support.mozilla.org/en-US/questions/new/firefox/form ...had been erased. I had to start again. Firefox is generally my favourite secure browser, but this issue needs to be fixed. Thanks AJ
