getting ‘your in-browser storage for MEGA is full’ error. mega isn’t letting me do anything until i fix it.
my actual mega account has plenty of storage left. this is something different.
what is ‘in-browser storage’ for MEGA? is this something i control or is it a MEGA setting? and what’s the fastest way to clear it without losing anything from my actual mega account?
also: does this mean i need to clear all my browser data or just something MEGA-specific? want to understand what gets cleared before i do anything.
the distinction between in-browser storage and actual cloud storage being completely separate is the key thing to understand. the error sounds like you’re running out of cloud space but it has nothing to do with your account quota. clearing the browser’s local data for mega.nz resolves it immediately.
the mega desktop app being the fix for persistent browser storage issues is the right long-term recommendation. it doesn’t use browser storage at all so it sidesteps the problem entirely. for people who regularly download large files from mega, the desktop app is a better choice than the web interface anyway.
The site-specific data deletion in Chrome’s settings being more targeted than clearing all browsing data is worth knowing. You don’t have to clear cache for everything – you can find mega.nz specifically and delete only its stored data. The rest of your browser cache stays intact.
MEGA uses your browser’s local storage (not your MEGA account storage quota) for caching, temporary file chunks during upload/download, and some session data. this is separate from your cloud storage.
to clear it without affecting your account data:
clear site data for MEGA specifically in chrome: settings > privacy and security > site settings > view permissions and data stored across sites > search for mega.nz > click the result > clear data. this removes only MEGA’s local browser storage, not your cloud files.
in firefox: settings > privacy & security > cookies and site data > manage data > search mega > remove.
after clearing, you’ll need to log back into MEGA in the browser.
if you use the MEGA browser extension: the extension also uses some local storage. disabling and re-enabling the extension clears its cache.
why it fills up: large file operations (especially interrupted uploads or downloads) can leave partial data in local storage. MEGA sometimes doesn’t clean these up automatically.
does clearing it delete anything from your mega account? no. your cloud files are on MEGA’s servers. local storage is only temporary browser-side data. clearing it is safe.
This error appearing specifically after large downloads is the pattern to note. Each large file download fills up a portion of browser storage. Multiple large downloads in sequence accumulate until the limit is hit. The fix is always the same – clear MEGA’s browser data – but knowing the trigger helps set expectations.
