The final push to start using Firefox over Chrome on Android might finally be thanks to the enormous selection of add-ons (Firefox’s version of extensions) coming out next month. Chrome doesn’t offer native support for extensions in its mobile app. Also, better security.
That doesn’t bring your info over from Chrome though
All browsers (on desktop) have a “import from other browser” step on initial setup. Just follow that, import your bookmarks, bob’s your uncle.
In fact, a quick Internet query brings up the relevant support article: https://support.mozilla.org/en-US/kb/import-bookmarks-google-chrome
I didn’t realise it could bring your history too. That’s handy to know, thanks :)
