I'd like to have check spelling permanent instead of enabling it on every other website manually. If I go to a different website and come back, spelling gets disabled. Of course, if I visit any new different website, spelling is disabled.
If you want Spelling to be automatically enabled always and on every page, you have to enable it in Settings or manually add this line to the prefs.js file (NB! Firefox must be completely closed while editing this file). Here it is Code: user_pref("services.sync.prefs.sync-seen.layout.spellcheckDefault", true); More possible choices Code: https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker
editing prefs real time will instantly working, no restart required. your line is futile, go about:config and create or modify that pref. your line is better written in a user.js near to prefs.js to be loaded each firefox start to force it present if otherwise altered. ok, your pref do not exist any more if so https://searchfox.org/mozilla-central/search?q=services.sync.prefs.sync-seen.layout.spellcheckDefault&path=&case=false®exp=true you mean "services.sync.prefs.sync.layout.spellcheckDefault" ?
Yes, you got it absolutely right. That's exactly how it is. And how you make those changes doesn't matter at all. It also doesn't matter if you save the file as prefs.js or user.js. By default, Firefox stores them all in prefs.js. But, of course, for the average user, it is also available on the Settings page, and it is easiest to do it from there.
missed it? not all editors are capable to edit such file. and editing in about:config is real time, you do not need to restart firefox. trust me. thats so true. but to mention it: some options changes more than one pref. example --> tracking protection (default/strong/custom)
Both settings were enabled by default and still: I expect both languages to be enabled permanently, maybe I expect too much.
firefox wont enable more than one https://support.mozilla.org/en-US/questions/1365130 currently there exist no mixed dictionary, you need another extension.
But it has been fixed for FF 100 and newer it says, no? Actually I can check both dictionaries manually and both stay enabled as long I don't change to another page so what am I missing? https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker Oh no! I do not want another extension to add in my browser. I'd like to know which it is though. I mean in case I needed to install it to stop struggling with right clicking every time.
