Hi,

I am a French-speaking user and after my first installation, Firefox was in English, I changed the settings in the software. However after each update this one goes back to English. Is there a way for the parameters to be kept ?

Firefox update today and same issue

a month later

Just wanted to say that I have the same issue because it happened again this weekend. I use my system in portuguese but every update makes Firefox go back to english and it removes my language as an option.

Would anyone who experiences this bug please show your firefox localization settings by putting about:support in the address bar, and then scrolling to the bottom.

You should see a table something like this: (yours should have locales other than en-us)

Hello,

here's mine:

As someone already mentioned, my firefox also seems to switch back to english locale only on major version updates. Whenever that happens I just head to the languages section of about:addons and hit the check for updates option of the upper right corner settings cog icon as shown and highlighted on the screenshot below (it's in czech, sorry!) to fix the issue. Sometimes firefox restart is needed to have all of the strings fixed (some remain in english even after the language update), other than that it works just fine though and switches firefox back to czech automatically.

I get this too, my firefox is always switching me from en-GB to en-US.

Application Settings
Requested Locales 	["en-US"]
Available Locales 	["ka","gu-IN","tl","hr","ff","gl","et","it","sl","cak","nn-NO","son","hi-IN","pa-IN","eu","az","lt","en-US","ca-valencia","gn","be","kab","lij","nb-NO","ne-NP","sv-SE","es-MX","zh-CN","dsb","fi","ach","lv","my","br","vi","pl","ms","en-GB","rm","ja","uz","ar","hsb","sr","th","gd","ast","ta","ur","trs","te","hy-AM","mr","pt-BR","uk","eo","nl","mk","ru","bs","af","ga-IE","da","pt-PT","cs","fr","kk","bn","el","fa","he","kn","an","bg","km","sk","fy-NL","si","ko","de","sq","xh","zh-TW","cy","id","es-CL","is","es-AR","ro","ca","hu","oc","en-CA","ia","tr","es-ES"]

Regional Preferences 	["en-GB"]
Default Locale 	"en-US"

It's the same case for me.
When Firefox change of principle version (for instance, update version v.117 to v.118), I must reestablish the language settings en French via the appropriate menu.
After this, these are below my firefox localization settings:

This is mine. I'm also noticing everyone here has "en-US" as default locale 🤔. I think this shouldn't be the case as I have "Português (BR)" as the first language in the settings list

    "everyone here has "en-US" as default locale" - that's something Firefox forces upon us, has been like this for years and I hate it.
    You can't even get rid of "en-US" as one of the languages the browser has saved in its settings!

      The best chance we have of getting this fixed is if someone creates reproduction steps for us. Create a new KVM VM (using gnome-boxes or virt-manager), install a 4.4 ISO, and document step-by-step how you reproduce the issue. With that information we can actually figure out the cause of this and fix it (assuming it's not an upstream issue).

        So, I made a test with Gnome Boxes to install Solus Budgie 4.4 in French.
        After installing, the kernel is in version 6.3.8-240 and Firefox, in version 114.0.1.

        Then, I update 324 packages (1,26 GiB), then I reboot my computer.

        I hope these elements will help you, remaining at your disposal.

          This issue has been resolved in unstable and the fix will be in the next sync. Firefox will now automatically adapt to the system locale, and this setting should persist through future updates. You will not need to install any languages manually, the correct one will be installed and configured automatically. Note that existing Firefox profiles will be in English the first time you launch them after the update, but subsequent launches should be in the correct language.

          This issue should be solved for all users that do an update now. Note that if you have an existing Firefox profile that it might launch in English the first time you launch it after the update, but if you close it and re-open it it should be in your system language.
