Flash/Shockwave crash a common story for Linux on all browsers.
Btw I disagree.
Vanilla and Strawberry can't be used for mud facials like chocolate - Opera, is the most gracious, has an extension for speed dial reminders, has a long click on link to create background tabs, has stacks
Chocolate and Strawberry tend to ruin Coffee unlike Vanilla - Firefox overall has the best cross-platform stability and integration. It has unique add-ons like Scrapbook Plus. It has the most advanced session manager. With less than 50 tabs, Firefox is still better than both Chrome and Opera
Strawberry may not be as unique as Vanilla or as robust as Chocolate but it mixes well with both - Chrome's link to google account means it has the most guaranteed "you already have this account" for online sync, it also has some unique feed readers like FeedSquare and News Factory that is not just your regular RSS Reader Prettifier. It has unique to-do lists like My Time Organizer and Do it Later Alligator. It may crash pages but most session managers for it also treat session links like checkboxes. Coincidentally it also has context for extension icon management and it has the most unique and colorful library synching with the look of tablets.
If you're a dedicated web reader, it really has been "locked in to this feature or no alternative" for a while with the exception of IE and that's only because of Maxthon. If Flock is not dead, it would have been offering users another unique sidebar taste. (But god I hate how it slows down and the orange icons).
2013 Browsers Wars are the Browser PIM wars i.e. the Extension and Exclusive Feature Wars
If you use Zotero, you would be highly leaning towards Firefox.
If you play HTML5 games, the apps of Chrome is much more friendly.
If you like native smart drag, Maxthon.
If you like fit width to screen, you go Opera
...and that's just some of the examples of recommended extensions for recommended programs. It's the coders nowadays that have the simpler choice. Regular users have to use, experience and browse all the new extensions all the time as blogs have gone totally commercial on the list of top extensions to install on browsers thread while user reviewers have been extremely harsh on one end while extension developers have gone through a dry spell of resurrecting old extensions. Anything that's banned from Google Chrome's extension list probably won't be blogged or praised. Anything that has barely any reviews on Firefox Add-ons probably won't have much people pointing out the existence of that extension. Anything that's on Opera will be mostly ignored. Maxthon won't even make a dent.
