Job hunting while still employed has an awkward browser problem. Your LinkedIn tab is logged into the account your manager might see. Your cookies remember every job listing you opened, so ads for "we're hiring" start showing up on unrelated sites you visit later. If you're testing a second Naukri or Indeed account, or just don't want your job-search browsing bleeding into the profile you use for everything else, the usual fix is a separate browser or a private window. Firefox has a better one built in, and it's specific to Firefox: Multi-Account Containers.
What a container actually does
A container is an isolated cookie jar inside one browser window. Tabs assigned to a "Work" container and tabs assigned to a "Job Hunt" container can be logged into the same site under two different accounts at the same time, in two tabs sitting right next to each other, because each container keeps its own cookies, local storage, and site data completely separate. No new browser install, no separate profile folder to manage, no signing out of one account to check the other.
This isn't a built-in Firefox feature by default; it ships as Mozilla's own free extension, Firefox Multi-Account Containers. It's a first-party Mozilla add-on, not a third-party workaround, which is part of why it's worth trusting with something as sensitive as a job search you'd rather keep quiet.
Why it's worth the two minutes of setup for a job search specifically
- Your current employer's tab stays untouched. If you're logged into LinkedIn for work reasons (checking messages, posting on a company page), a separate container means your job-search activity never shares a session with that tab.
- Recommendation algorithms stop cross-contaminating. LinkedIn and job boards personalize what they show you based on what you've clicked. A dedicated container means your "actively browsing senior roles at competitors" signal doesn't quietly shape what your main, everyday browsing session sees you as interested in.
- Testing a second account is trivial. Some people keep a secondary Naukri or Indeed profile for a cleaner application history. A container makes both accounts usable side by side without constant logout and login.
- Closing the container clears the trail. Assign the container to "delete data when last tab closes" in the extension's settings, and every cookie from that search session is gone when you're done, without touching anything else in your browser.
Setting up a Job Hunt container
- Install Firefox Multi-Account Containers from Firefox Add-ons.
- Click its toolbar icon and choose "New Container," name it something like "Job Hunt," and pick a color so the tab border makes it obvious at a glance which container you're in.
- Open LinkedIn, Naukri, or Indeed, right-click the tab, and choose "Open this site in a new container" or select the container from the toolbar icon before navigating there. Firefox remembers the assignment, so the site opens in that container by default going forward.
- Optional: in the container's settings, turn on "Always Open in [Job Hunt]" for each career site, so an accidental click on a LinkedIn link never lands in your main session by mistake.
Where autofill fits into this
Firefox extensions run per tab based on which site they're set to match, not per container. That means an autofill extension like ApplyCandid injects into a LinkedIn tab the exact same way whether that tab lives in your default identity or a Job Hunt container, because the content script matches the URL, not the cookie jar it's sitting in. You get the isolation benefit of a container and the autofill behavior of a normal tab at the same time, with nothing to configure on the extension's side.
One thing containers don't do
A container isolates cookies and site data, not network traffic or your employer's own device monitoring. If you're job hunting on a company laptop, containers don't change what IT can see at the network or endpoint level, and that's a genuinely different problem with a different fix (a personal device, generally). What containers solve well is the much more common case: browsing on your own machine, on your own time, without your job search quietly leaking into the browsing profile your day job already knows about.
Set up your Job Hunt container, then let autofill do the typing.
